+Backward incompatibilities:
+ * changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
+ * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
+ * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
+
+ * added self as a special variable that refers to the current template (useful for importing macros from the current template)
+ * added Twig_Template instance support to the include tag
+ * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
+ * added a grammar sub-framework to ease the creation of custom tags
+ * fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
+ * removed the Twig_Resource::resolveMissingFilter() method
+ * fixed the filter tag which did not apply filtering to included files
+ * added a bunch of unit tests
+ * added a bunch of phpdoc
+ * added a sandbox tag in the sandbox extension
+ * changed the date filter to support any date format supported by DateTime
+ * added strict_variable setting to throw an exception when an invalid variable is used in a template (disabled by default)
+ * added the lexer, parser, and compiler as arguments to the Twig_Environment constructor
+ * changed the cache option to only accepts an explicit path to a cache directory or false
+ * added a way to add token parsers, filters, and visitors without creating an extension
+ * added three interfaces: Twig_NodeInterface, Twig_TokenParserInterface, and Twig_FilterInterface
+ * changed the generated code to match the new coding standards
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
+ * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
+
+# 0.9.6 (2010-05-12)
+
+ * fixed variables defined outside a loop and for which the value changes in a for loop
+ * fixed the test suite for PHP 5.2 and older versions of PHPUnit
+ * added support for __call() in expression resolution
+ * fixed node visiting for macros (macros are now visited by visitors as any other node)
+ * fixed nested block definitions with a parent call (rarely useful but nonetheless supported now)
+ * added the cycle filter
+ * fixed the Lexer when mbstring.func_overload is used with an mbstring.internal_encoding different from ASCII
+ * added a long-syntax for the set tag ({% set foo %}...{% endset %})
+ * unit tests are now powered by PHPUnit
+ * added support for gettext via the `i18n` extension
+ * fixed twig_capitalize_string_filter() and fixed twig_length_filter() when used with UTF-8 values
+ * added a more useful exception if an if tag is not closed properly
+ * added support for escaping strategy in the autoescape tag
+ * fixed lexer when a template has a big chunk of text between/in a block
+
+# 0.9.5 (2010-01-20)
+
+As for any new release, don't forget to remove all cached templates after
+upgrading.
+
+If you have defined custom filters, you MUST upgrade them for this release. To
+upgrade, replace "array" with "new Twig_Filter_Function", and replace the
+environment constant by the "needs_environment" option:
+
+  // before
+  'even'   => array('twig_is_even_filter', false),
+  'escape' => array('twig_escape_filter', true),
+
+  // after
+  'even'   => new Twig_Filter_Function('twig_is_even_filter'),
+  'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
+
+If you have created NodeTransformer classes, you will need to upgrade them to
+the new interface (please note that the interface is not yet considered
+stable).
+
+ * fixed list nodes that did not extend the Twig_NodeListInterface
+ * added the "without loop" option to the for tag (it disables the generation of the loop variable)
+ * refactored node transformers to node visitors
+ * fixed automatic-escaping for blocks
+ * added a way to specify variables to pass to an included template
+ * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
+ * improved the filter system to allow object methods to be used as filters
+ * changed the Array and String loaders to actually make use of the cache mechanism
+ * included the default filter function definitions in the extension class files directly (Core, Escaper)
+ * added the // operator (like the floor() PHP function)
+ * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
+ * added the in operator (as a syntactic sugar for the in filter)
+ * added the following filters in the Core extension: in, range
+ * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
+ * enhanced some error messages to provide better feedback in case of parsing errors
+
+# 0.9.4 (2009-12-02)
+
+If you have custom loaders, you MUST upgrade them for this release: The
+Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
+been changed (see the source code for more information or the documentation).
+
+ * added support for DateTime instances for the date filter
+ * fixed loop.last when the array only has one item
+ * made it possible to insert newlines in tag and variable blocks
+ * fixed a bug when a literal '\n' were present in a template text
+ * fixed bug when the filename of a template contains */
+ * refactored loaders
+
+# 0.9.3 (2009-11-11)
+
+This release is NOT backward compatible with the previous releases.
+
+  The loaders do not take the cache and autoReload arguments anymore. Instead,
+  the Twig_Environment class has two new options: cache and auto_reload.
+  Upgrading your code means changing this kind of code:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
+      $twig = new Twig_Environment($loader);
+
+  to something like this:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates');
+      $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+        'auto_reload' => true,
+      ));
+
+ * deprecated the "items" filter as it is not needed anymore
+ * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
+ * optimized template loading speed
+ * removed output when an error occurs in a template and render() is used
+ * made major speed improvements for loops (up to 300% on even the smallest loops)
+ * added properties as part of the sandbox mode
+ * added public properties support (obj.item can now be the item property on the obj object)
+ * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
+ * fixed bug when \ was used in HTML
+
+# 0.9.2 (2009-10-29)
+
+ * made some speed optimizations
+ * changed the cache extension to .php
+ * added a js escaping strategy
+ * added support for short block tag
+ * changed the filter tag to allow chained filters
+ * made lexer more flexible as you can now change the default delimiters
+ * added set tag
+ * changed default directory permission when cache dir does not exist (more secure)
+ * added macro support
+ * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
+ * made Twig_Autoloader::autoload() a static method
+ * avoid writing template file if an error occurs
+ * added $ escaping when outputting raw strings
+ * enhanced some error messages to ease debugging
+ * fixed empty cache files when the template contains an error
+
+# 0.9.1 (2009-10-14)
+
+  * fixed a bug in PHP 5.2.6
+  * fixed numbers with one than one decimal
+  * added support for method calls with arguments ({{ foo.bar('a', 43) }})
+  * made small speed optimizations
+  * made minor tweaks to allow better extensibility and flexibility
+
+# 0.9.0 (2009-10-12)
+
+ * Initial release

+Twig, the flexible, fast, and secure template language for PHP
+==============================================================
+
+Twig is a template language for PHP, released under the new BSD license (code
+and documentation).
+
+Twig uses a syntax similar to the Django and Jinja template languages which
+inspired the Twig runtime environment.

+Extending Twig
+==============
+
+Twig can be extended in many ways; you can add extra tags, filters, tests,
+operators, global variables, and functions. You can even extend the parser
+itself with node visitors.
+
+.. note::
+
+    The first section of this chapter describes how to extend Twig. If you want
+    to reuse your changes in different projects or if you want to share them
+    with others, you should then create an extension as described in the
+    following section.
+
+.. caution::
+
+    When extending Twig without creating an extension, Twig won't be able to
+    recompile your templates when the PHP code is updated. To see your changes
+    in real-time, either disable template caching or package your code into an
+    extension (see the next section of this chapter).
+
+Before extending Twig, you must understand the differences between all the
+different possible extension points and when to use them.
+
+First, remember that Twig has two main language constructs:
+
+* ``{{ }}``: used to print the result of an expression evaluation;
+
+* ``{% %}``: used to execute statements.
+
+To understand why Twig exposes so many extension points, let's see how to
+implement a *Lorem ipsum* generator (it needs to know the number of words to
+generate).
+
+You can use a ``lipsum`` *tag*:
+
+.. code-block:: twig
+
+    {% lipsum 40 %}
+
+That works, but using a tag for ``lipsum`` is not a good idea for at least
+three main reasons:
+
+* ``lipsum`` is not a language construct;
+* The tag outputs something;
+* The tag is not flexible as you cannot use it in an expression:
+
+  .. code-block:: twig
+
+      {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
+
+In fact, you rarely need to create tags; and that's good news because tags are
+the most complex extension point.
+
+Now, let's use a ``lipsum`` *filter*:
+
+.. code-block:: twig
+
+    {{ 40|lipsum }}
+
+Again, it works. But a filter should transform the passed value to something
+else. Here, we use the value to indicate the number of words to generate (so,
+``40`` is an argument of the filter, not the value we want to transform).
+
+Next, let's use a ``lipsum`` *function*:
+
+.. code-block:: twig
+
+    {{ lipsum(40) }}
+
+Here we go. For this specific example, the creation of a function is the
+extension point to use. And you can use it anywhere an expression is accepted:
+
+.. code-block:: twig
+
+    {{ 'some text' ~ lipsum(40) ~ 'some more text' }}
+
+    {% set lipsum = lipsum(40) %}
+
+Lastly, you can also use a *global* object with a method able to generate lorem
+ipsum text:
+
+.. code-block:: twig
+
+    {{ text.lipsum(40) }}
+
+As a rule of thumb, use functions for frequently used features and global
+objects for everything else.
+
+Keep in mind the following when you want to extend Twig:
+
+========== ========================== ========== =========================
+What?      Implementation difficulty? How often? When?
+========== ========================== ========== =========================
+*macro*    simple                     frequent   Content generation
+*global*   simple                     frequent   Helper object
+*function* simple                     frequent   Content generation
+*filter*   simple                     frequent   Value transformation
+*tag*      complex                    rare       DSL language construct
+*test*     simple                     rare       Boolean decision
+*operator* simple                     rare       Values transformation
+========== ========================== ========== =========================
+
+Globals
+-------
+
+A global variable is like any other template variable, except that it's
+available in all templates and macros::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->addGlobal('text', new Text());
+
+You can then use the ``text`` variable anywhere in a template:
+
+.. code-block:: twig
+
+    {{ text.lipsum(40) }}
+
+Filters
+-------
+
+Creating a filter consists of associating a name with a PHP callable::
+
+    // an anonymous function
+    $filter = new \Twig\TwigFilter('rot13', function ($string) {
+        return str_rot13($string);
+    });
+
+    // or a simple PHP function
+    $filter = new \Twig\TwigFilter('rot13', 'str_rot13');
+
+    // or a class static method
+    $filter = new \Twig\TwigFilter('rot13', ['SomeClass', 'rot13Filter']);
+    $filter = new \Twig\TwigFilter('rot13', 'SomeClass::rot13Filter');
+
+    // or a class method
+    $filter = new \Twig\TwigFilter('rot13', [$this, 'rot13Filter']);
+    // the one below needs a runtime implementation (see below for more information)
+    $filter = new \Twig\TwigFilter('rot13', ['SomeClass', 'rot13Filter']);
+
+The first argument passed to the ``\Twig\TwigFilter`` constructor is the name of the
+filter you will use in templates and the second one is the PHP callable to
+associate with it.
+
+Then, add the filter to the Twig environment::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->addFilter($filter);
+
+And here is how to use it in a template:
+
+.. code-block:: twig
+
+    {{ 'Twig'|rot13 }}
+
+    {# will output Gjvt #}
+
+When called by Twig, the PHP callable receives the left side of the filter
+(before the pipe ``|``) as the first argument and the extra arguments passed
+to the filter (within parentheses ``()``) as extra arguments.
+
+For instance, the following code:
+
+.. code-block:: twig
+
+    {{ 'TWIG'|lower }}
+    {{ now|date('d/m/Y') }}
+
+is compiled to something like the following::
+
+    <?php echo strtolower('TWIG') ?>
+    <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
+
+The ``\Twig\TwigFilter`` class takes an array of options as its last argument::
+
+    $filter = new \Twig\TwigFilter('rot13', 'str_rot13', $options);
+
+Environment-aware Filters
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current environment instance in your filter, set the
+``needs_environment`` option to ``true``; Twig will pass the current
+environment as the first argument to the filter call::
+
+    $filter = new \Twig\TwigFilter('rot13', function (\Twig\Environment $env, $string) {
+        // get the current charset for instance
+        $charset = $env->getCharset();
+
+        return str_rot13($string);
+    }, ['needs_environment' => true]);
+
+Context-aware Filters
+~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current context in your filter, set the
+``needs_context`` option to ``true``; Twig will pass the current context as
+the first argument to the filter call (or the second one if
+``needs_environment`` is also set to ``true``)::
+
+    $filter = new \Twig\TwigFilter('rot13', function ($context, $string) {
+        // ...
+    }, ['needs_context' => true]);
+
+    $filter = new \Twig\TwigFilter('rot13', function (\Twig\Environment $env, $context, $string) {
+        // ...
+    }, ['needs_context' => true, 'needs_environment' => true]);
+
+Automatic Escaping
+~~~~~~~~~~~~~~~~~~
+
+If automatic escaping is enabled, the output of the filter may be escaped
+before printing. If your filter acts as an escaper (or explicitly outputs HTML
+or JavaScript code), you will want the raw output to be printed. In such a
+case, set the ``is_safe`` option::
+
+    $filter = new \Twig\TwigFilter('nl2br', 'nl2br', ['is_safe' => ['html']]);
+
+Some filters may need to work on input that is already escaped or safe, for
+example when adding (safe) HTML tags to originally unsafe output. In such a
+case, set the ``pre_escape`` option to escape the input data before it is run
+through your filter::
+
+    $filter = new \Twig\TwigFilter('somefilter', 'somefilter', ['pre_escape' => 'html', 'is_safe' => ['html']]);
+
+Variadic Filters
+~~~~~~~~~~~~~~~~
+
+When a filter should accept an arbitrary number of arguments, set the
+``is_variadic`` option to ``true``; Twig will pass the extra arguments as the
+last argument to the filter call as an array::
+
+    $filter = new \Twig\TwigFilter('thumbnail', function ($file, array $options = []) {
+        // ...
+    }, ['is_variadic' => true]);
+
+Be warned that :ref:`named arguments <named-arguments>` passed to a variadic
+filter cannot be checked for validity as they will automatically end up in the
+option array.
+
+Dynamic Filters
+~~~~~~~~~~~~~~~
+
+A filter name containing the special ``*`` character is a dynamic filter and
+the ``*`` part will match any string::
+
+    $filter = new \Twig\TwigFilter('*_path', function ($name, $arguments) {
+        // ...
+    });
+
+The following filters are matched by the above defined dynamic filter:
+
+* ``product_path``
+* ``category_path``
+
+A dynamic filter can define more than one dynamic parts::
+
+    $filter = new \Twig\TwigFilter('*_path_*', function ($name, $suffix, $arguments) {
+        // ...
+    });
+
+The filter receives all dynamic part values before the normal filter arguments,
+but after the environment and the context. For instance, a call to
+``'foo'|a_path_b()`` will result in the following arguments to be passed to the
+filter: ``('a', 'b', 'foo')``.
+
+Deprecated Filters
+~~~~~~~~~~~~~~~~~~
+
+You can mark a filter as being deprecated by setting the ``deprecated`` option
+to ``true``. You can also give an alternative filter that replaces the
+deprecated one when that makes sense::
+
+    $filter = new \Twig\TwigFilter('obsolete', function () {
+        // ...
+    }, ['deprecated' => true, 'alternative' => 'new_one']);
+
+When a filter is deprecated, Twig emits a deprecation notice when compiling a
+template using it. See :ref:`deprecation-notices` for more information.
+
+Functions
+---------
+
+Functions are defined in the exact same way as filters, but you need to create
+an instance of ``\Twig\TwigFunction``::
+
+    $twig = new \Twig\Environment($loader);
+    $function = new \Twig\TwigFunction('function_name', function () {
+        // ...
+    });
+    $twig->addFunction($function);
+
+Functions support the same features as filters, except for the ``pre_escape``
+and ``preserves_safety`` options.
+
+Tests
+-----
+
+Tests are defined in the exact same way as filters and functions, but you need
+to create an instance of ``\Twig\TwigTest``::
+
+    $twig = new \Twig\Environment($loader);
+    $test = new \Twig\TwigTest('test_name', function () {
+        // ...
+    });
+    $twig->addTest($test);
+
+Tests allow you to create custom application specific logic for evaluating
+boolean conditions. As a simple example, let's create a Twig test that checks if
+objects are 'red'::
+
+    $twig = new \Twig\Environment($loader);
+    $test = new \Twig\TwigTest('red', function ($value) {
+        if (isset($value->color) && $value->color == 'red') {
+            return true;
+        }
+        if (isset($value->paint) && $value->paint == 'red') {
+            return true;
+        }
+        return false;
+    });
+    $twig->addTest($test);
+
+Test functions must always return ``true``/``false``.
+
+When creating tests you can use the ``node_class`` option to provide custom test
+compilation. This is useful if your test can be compiled into PHP primitives.
+This is used by many of the tests built into Twig::
+
+    namespace App;
+    
+    use Twig\Environment;
+    use Twig\Node\Expression\TestExpression;
+    use Twig\TwigTest;
+    
+    $twig = new Environment($loader);
+    $test = new TwigTest(
+        'odd',
+        null,
+        ['node_class' => OddTestExpression::class]);
+    $twig->addTest($test);
+
+    class OddTestExpression extends TestExpression
+    {
+        public function compile(\Twig\Compiler $compiler)
+        {
+            $compiler
+                ->raw('(')
+                ->subcompile($this->getNode('node'))
+                ->raw(' % 2 != 0')
+                ->raw(')')
+            ;
+        }
+    }
+
+The above example shows how you can create tests that use a node class. The node
+class has access to one sub-node called ``node``. This sub-node contains the
+value that is being tested. When the ``odd`` filter is used in code such as:
+
+.. code-block:: twig
+
+    {% if my_value is odd %}
+
+The ``node`` sub-node will contain an expression of ``my_value``. Node-based
+tests also have access to the ``arguments`` node. This node will contain the
+various other arguments that have been provided to your test.
+
+If you want to pass a variable number of positional or named arguments to the
+test, set the ``is_variadic`` option to ``true``. Tests support dynamic
+names (see dynamic filters for the syntax).
+
+Tags
+----
+
+One of the most exciting features of a template engine like Twig is the
+possibility to define new **language constructs**. This is also the most complex
+feature as you need to understand how Twig's internals work.
+
+Most of the time though, a tag is not needed:
+
+* If your tag generates some output, use a **function** instead.
+
+* If your tag modifies some content and returns it, use a **filter** instead.
+
+  For instance, if you want to create a tag that converts a Markdown formatted
+  text to HTML, create a ``markdown`` filter instead:
+
+  .. code-block:: twig
+
+      {{ '**markdown** text'|markdown }}
+
+  If you want use this filter on large amounts of text, wrap it with the
+  :doc:`apply <tags/apply>` tag:
+
+  .. code-block:: twig
+
+      {% apply markdown %}
+      Title
+      =====
+
+      Much better than creating a tag as you can **compose** filters.
+      {% endapply %}
+
+* If your tag does not output anything, but only exists because of a side
+  effect, create a **function** that returns nothing and call it via the
+  :doc:`filter <tags/do>` tag.
+
+  For instance, if you want to create a tag that logs text, create a ``log``
+  function instead and call it via the :doc:`do <tags/do>` tag:
+
+  .. code-block:: twig
+
+      {% do log('Log some things') %}
+
+If you still want to create a tag for a new language construct, great!
+
+Let's create a ``set`` tag that allows the definition of simple variables from
+within a template. The tag can be used like follows:
+
+.. code-block:: twig
+
+    {% set name = "value" %}
+
+    {{ name }}
+
+    {# should output value #}
+
+.. note::
+
+    The ``set`` tag is part of the Core extension and as such is always
+    available. The built-in version is slightly more powerful and supports
+    multiple assignments by default.
+
+Three steps are needed to define a new tag:
+
+* Defining a Token Parser class (responsible for parsing the template code);
+
+* Defining a Node class (responsible for converting the parsed code to PHP);
+
+* Registering the tag.
+
+Registering a new tag
+~~~~~~~~~~~~~~~~~~~~~
+
+Add a tag by calling the ``addTokenParser`` method on the ``\Twig\Environment``
+instance::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->addTokenParser(new Project_Set_TokenParser());
+
+Defining a Token Parser
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now, let's see the actual code of this class::
+
+    class Project_Set_TokenParser extends \Twig\TokenParser\AbstractTokenParser
+    {
+        public function parse(\Twig\Token $token)
+        {
+            $parser = $this->parser;
+            $stream = $parser->getStream();
+
+            $name = $stream->expect(\Twig\Token::NAME_TYPE)->getValue();
+            $stream->expect(\Twig\Token::OPERATOR_TYPE, '=');
+            $value = $parser->getExpressionParser()->parseExpression();
+            $stream->expect(\Twig\Token::BLOCK_END_TYPE);
+
+            return new Project_Set_Node($name, $value, $token->getLine(), $this->getTag());
+        }
+
+        public function getTag()
+        {
+            return 'set';
+        }
+    }
+
+The ``getTag()`` method must return the tag we want to parse, here ``set``.
+
+The ``parse()`` method is invoked whenever the parser encounters a ``set``
+tag. It should return a ``\Twig\Node\Node`` instance that represents the node (the
+``Project_Set_Node`` calls creating is explained in the next section).
+
+The parsing process is simplified thanks to a bunch of methods you can call
+from the token stream (``$this->parser->getStream()``):
+
+* ``getCurrent()``: Gets the current token in the stream.
+
+* ``next()``: Moves to the next token in the stream, *but returns the old one*.
+
+* ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
+  the current token is of a particular type or value (or both). The value may be an
+  array of several possible values.
+
+* ``expect($type[, $value[, $message]])``: If the current token isn't of the given
+  type/value a syntax error is thrown. Otherwise, if the type and value are correct,
+  the token is returned and the stream moves to the next token.
+
+* ``look()``: Looks at the next token without consuming it.
+
+Parsing expressions is done by calling the ``parseExpression()`` like we did for
+the ``set`` tag.
+
+.. tip::
+
+    Reading the existing ``TokenParser`` classes is the best way to learn all
+    the nitty-gritty details of the parsing process.
+
+Defining a Node
+~~~~~~~~~~~~~~~
+
+The ``Project_Set_Node`` class itself is quite short::
+
+    class Project_Set_Node extends \Twig\Node\Node
+    {
+        public function __construct($name, \Twig\Node\Expression\AbstractExpression $value, $line, $tag = null)
+        {
+            parent::__construct(['value' => $value], ['name' => $name], $line, $tag);
+        }
+
+        public function compile(\Twig\Compiler $compiler)
+        {
+            $compiler
+                ->addDebugInfo($this)
+                ->write('$context[\''.$this->getAttribute('name').'\'] = ')
+                ->subcompile($this->getNode('value'))
+                ->raw(";\n")
+            ;
+        }
+    }
+
+The compiler implements a fluid interface and provides methods that helps the
+developer generate beautiful and readable PHP code:
+
+* ``subcompile()``: Compiles a node.
+
+* ``raw()``: Writes the given string as is.
+
+* ``write()``: Writes the given string by adding indentation at the beginning
+  of each line.
+
+* ``string()``: Writes a quoted string.
+
+* ``repr()``: Writes a PHP representation of a given value (see
+  ``\Twig\Node\ForNode`` for a usage example).
+
+* ``addDebugInfo()``: Adds the line of the original template file related to
+  the current node as a comment.
+
+* ``indent()``: Indents the generated code (see ``\Twig\Node\BlockNode`` for a
+  usage example).
+
+* ``outdent()``: Outdents the generated code (see ``\Twig\Node\BlockNode`` for a
+  usage example).
+
+.. _creating_extensions:
+
+Creating an Extension
+---------------------
+
+The main motivation for writing an extension is to move often used code into a
+reusable class like adding support for internationalization. An extension can
+define tags, filters, tests, operators, functions, and node visitors.
+
+Most of the time, it is useful to create a single extension for your project,
+to host all the specific tags and filters you want to add to Twig.
+
+.. tip::
+
+    When packaging your code into an extension, Twig is smart enough to
+    recompile your templates whenever you make a change to it (when
+    ``auto_reload`` is enabled).
+
+An extension is a class that implements the following interface::
+
+    interface \Twig\Extension\ExtensionInterface
+    {
+        /**
+         * Returns the token parser instances to add to the existing list.
+         *
+         * @return \Twig\TokenParser\TokenParserInterface[]
+         */
+        public function getTokenParsers();
+
+        /**
+         * Returns the node visitor instances to add to the existing list.
+         *
+         * @return \Twig\NodeVisitor\NodeVisitorInterface[]
+         */
+        public function getNodeVisitors();
+
+        /**
+         * Returns a list of filters to add to the existing list.
+         *
+         * @return \Twig\TwigFilter[]
+         */
+        public function getFilters();
+
+        /**
+         * Returns a list of tests to add to the existing list.
+         *
+         * @return \Twig\TwigTest[]
+         */
+        public function getTests();
+
+        /**
+         * Returns a list of functions to add to the existing list.
+         *
+         * @return \Twig\TwigFunction[]
+         */
+        public function getFunctions();
+
+        /**
+         * Returns a list of operators to add to the existing list.
+         *
+         * @return array<array> First array of unary operators, second array of binary operators
+         */
+        public function getOperators();
+    }
+
+To keep your extension class clean and lean, inherit from the built-in
+``\Twig\Extension\AbstractExtension`` class instead of implementing the interface as it provides
+empty implementations for all methods::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+    }
+
+This extension does nothing for now. We will customize it in the next sections.
+
+You can save your extension anywhere on the filesystem, as all extensions must
+be registered explicitly to be available in your templates.
+
+You can register an extension by using the ``addExtension()`` method on your
+main ``Environment`` object::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->addExtension(new Project_Twig_Extension());
+
+.. tip::
+
+    The Twig core extensions are great examples of how extensions work.
+
+Globals
+~~~~~~~
+
+Global variables can be registered in an extension via the ``getGlobals()``
+method::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension implements \Twig\Extension\GlobalsInterface
+    {
+        public function getGlobals(): array
+        {
+            return [
+                'text' => new Text(),
+            ];
+        }
+
+        // ...
+    }
+
+Functions
+~~~~~~~~~
+
+Functions can be registered in an extension via the ``getFunctions()``
+method::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getFunctions()
+        {
+            return [
+                new \Twig\TwigFunction('lipsum', 'generate_lipsum'),
+            ];
+        }
+
+        // ...
+    }
+
+Filters
+~~~~~~~
+
+To add a filter to an extension, you need to override the ``getFilters()``
+method. This method must return an array of filters to add to the Twig
+environment::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getFilters()
+        {
+            return [
+                new \Twig\TwigFilter('rot13', 'str_rot13'),
+            ];
+        }
+
+        // ...
+    }
+
+Tags
+~~~~
+
+Adding a tag in an extension can be done by overriding the
+``getTokenParsers()`` method. This method must return an array of tags to add
+to the Twig environment::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getTokenParsers()
+        {
+            return [new Project_Set_TokenParser()];
+        }
+
+        // ...
+    }
+
+In the above code, we have added a single new tag, defined by the
+``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
+responsible for parsing the tag and compiling it to PHP.
+
+Operators
+~~~~~~~~~
+
+The ``getOperators()`` methods lets you add new operators. Here is how to add
+the ``!``, ``||``, and ``&&`` operators::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getOperators()
+        {
+            return [
+                [
+                    '!' => ['precedence' => 50, 'class' => \Twig\Node\Expression\Unary\NotUnary::class],
+                ],
+                [
+                    '||' => ['precedence' => 10, 'class' => \Twig\Node\Expression\Binary\OrBinary::class, 'associativity' => \Twig\ExpressionParser::OPERATOR_LEFT],
+                    '&&' => ['precedence' => 15, 'class' => \Twig\Node\Expression\Binary\AndBinary::class, 'associativity' => \Twig\ExpressionParser::OPERATOR_LEFT],
+                ],
+            ];
+        }
+
+        // ...
+    }
+
+Tests
+~~~~~
+
+The ``getTests()`` method lets you add new test functions::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getTests()
+        {
+            return [
+                new \Twig\TwigTest('even', 'twig_test_even'),
+            ];
+        }
+
+        // ...
+    }
+
+Definition vs Runtime
+~~~~~~~~~~~~~~~~~~~~~
+
+Twig filters, functions, and tests runtime implementations can be defined as
+any valid PHP callable:
+
+* **functions/static methods**: Simple to implement and fast (used by all Twig
+  core extensions); but it is hard for the runtime to depend on external
+  objects;
+
+* **closures**: Simple to implement;
+
+* **object methods**: More flexible and required if your runtime code depends
+  on external objects.
+
+The simplest way to use methods is to define them on the extension itself::
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        private $rot13Provider;
+
+        public function __construct($rot13Provider)
+        {
+            $this->rot13Provider = $rot13Provider;
+        }
+
+        public function getFunctions()
+        {
+            return [
+                new \Twig\TwigFunction('rot13', [$this, 'rot13']),
+            ];
+        }
+
+        public function rot13($value)
+        {
+            return $this->rot13Provider->rot13($value);
+        }
+    }
+
+This is very convenient but not recommended as it makes template compilation
+depend on runtime dependencies even if they are not needed (think for instance
+as a dependency that connects to a database engine).
+
+You can decouple the extension definitions from their runtime implementations by
+registering a ``\Twig\RuntimeLoader\RuntimeLoaderInterface`` instance on the
+environment that knows how to instantiate such runtime classes (runtime classes
+must be autoload-able)::
+
+    class RuntimeLoader implements \Twig\RuntimeLoader\RuntimeLoaderInterface
+    {
+        public function load($class)
+        {
+            // implement the logic to create an instance of $class
+            // and inject its dependencies
+            // most of the time, it means using your dependency injection container
+            if ('Project_Twig_RuntimeExtension' === $class) {
+                return new $class(new Rot13Provider());
+            } else {
+                // ...
+            }
+        }
+    }
+
+    $twig->addRuntimeLoader(new RuntimeLoader());
+
+.. note::
+
+    Twig comes with a PSR-11 compatible runtime loader
+    (``\Twig\RuntimeLoader\ContainerRuntimeLoader``).
+
+It is now possible to move the runtime logic to a new
+``Project_Twig_RuntimeExtension`` class and use it directly in the extension::
+
+    class Project_Twig_RuntimeExtension
+    {
+        private $rot13Provider;
+
+        public function __construct($rot13Provider)
+        {
+            $this->rot13Provider = $rot13Provider;
+        }
+
+        public function rot13($value)
+        {
+            return $this->rot13Provider->rot13($value);
+        }
+    }
+
+    class Project_Twig_Extension extends \Twig\Extension\AbstractExtension
+    {
+        public function getFunctions()
+        {
+            return [
+                new \Twig\TwigFunction('rot13', ['Project_Twig_RuntimeExtension', 'rot13']),
+                // or
+                new \Twig\TwigFunction('rot13', 'Project_Twig_RuntimeExtension::rot13'),
+            ];
+        }
+    }
+
+Testing an Extension
+--------------------
+
+Functional Tests
+~~~~~~~~~~~~~~~~
+
+You can create functional tests for extensions by creating the following file
+structure in your test directory::
+
+    Fixtures/
+        filters/
+            foo.test
+            bar.test
+        functions/
+            foo.test
+            bar.test
+        tags/
+            foo.test
+            bar.test
+    IntegrationTest.php
+
+The ``IntegrationTest.php`` file should look like this::
+
+    use Twig\Test\IntegrationTestCase;
+
+    class Project_Tests_IntegrationTest extends IntegrationTestCase
+    {
+        public function getExtensions()
+        {
+            return [
+                new Project_Twig_Extension1(),
+                new Project_Twig_Extension2(),
+            ];
+        }
+
+        public function getFixturesDir()
+        {
+            return __DIR__.'/Fixtures/';
+        }
+    }
+
+Fixtures examples can be found within the Twig repository
+`tests/Twig/Fixtures`_ directory.
+
+Node Tests
+~~~~~~~~~~
+
+Testing the node visitors can be complex, so extend your test cases from
+``\Twig\Test\NodeTestCase``. Examples can be found in the Twig repository
+`tests/Twig/Node`_ directory.
+
+.. _`tests/Twig/Fixtures`: https://github.com/twigphp/Twig/tree/3.x/tests/Fixtures

+Twig for Developers
+===================
+
+This chapter describes the API to Twig and not the template language. It will
+be most useful as reference to those implementing the template interface to
+the application and not those who are creating Twig templates.
+
+Basics
+------
+
+Twig uses a central object called the **environment** (of class
+``\Twig\Environment``). Instances of this class are used to store the
+configuration and extensions, and are used to load templates.
+
+Most applications create one ``\Twig\Environment`` object on application
+initialization and use that to load templates. In some cases, it might be useful
+to have multiple environments side by side, with different configurations.
+
+The typical way to configure Twig to load templates for an application looks
+roughly like this::
+
+    require_once '/path/to/vendor/autoload.php';
+
+    $loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
+    $twig = new \Twig\Environment($loader, [
+        'cache' => '/path/to/compilation_cache',
+    ]);
+
+This creates a template environment with a default configuration and a loader
+that looks up templates in the ``/path/to/templates/`` directory. Different
+loaders are available and you can also write your own if you want to load
+templates from a database or other resources.
+
+.. note::
+
+    Notice that the second argument of the environment is an array of options.
+    The ``cache`` option is a compilation cache directory, where Twig caches
+    the compiled templates to avoid the parsing phase for sub-sequent
+    requests. It is very different from the cache you might want to add for
+    the evaluated templates. For such a need, you can use any available PHP
+    cache library.
+
+Rendering Templates
+-------------------
+
+To load a template from a Twig environment, call the ``load()`` method which
+returns a ``\Twig\TemplateWrapper`` instance::
+
+    $template = $twig->load('index.html');
+
+To render the template with some variables, call the ``render()`` method::
+
+    echo $template->render(['the' => 'variables', 'go' => 'here']);
+
+.. note::
+
+    The ``display()`` method is a shortcut to output the rendered template.
+
+You can also load and render the template in one fell swoop::
+
+    echo $twig->render('index.html', ['the' => 'variables', 'go' => 'here']);
+
+If a template defines blocks, they can be rendered individually via the
+``renderBlock()`` call::
+
+    echo $template->renderBlock('block_name', ['the' => 'variables', 'go' => 'here']);
+
+.. _environment_options:
+
+Environment Options
+-------------------
+
+When creating a new ``\Twig\Environment`` instance, you can pass an array of
+options as the constructor second argument::
+
+    $twig = new \Twig\Environment($loader, ['debug' => true]);
+
+The following options are available:
+
+* ``debug`` *boolean*
+
+  When set to ``true``, the generated templates have a
+  ``__toString()`` method that you can use to display the generated nodes
+  (default to ``false``).
+
+* ``charset`` *string* (defaults to ``utf-8``)
+
+  The charset used by the templates.
+
+* ``cache`` *string* or ``false``
+
+  An absolute path where to store the compiled templates, or
+  ``false`` to disable caching (which is the default).
+
+* ``auto_reload`` *boolean*
+
+  When developing with Twig, it's useful to recompile the
+  template whenever the source code changes. If you don't provide a value for
+  the ``auto_reload`` option, it will be determined automatically based on the
+  ``debug`` value.
+
+* ``strict_variables`` *boolean*
+
+  If set to ``false``, Twig will silently ignore invalid
+  variables (variables and or attributes/methods that do not exist) and
+  replace them with a ``null`` value. When set to ``true``, Twig throws an
+  exception instead (default to ``false``).
+
+* ``autoescape`` *string*
+
+  Sets the default auto-escaping strategy (``name``, ``html``, ``js``, ``css``,
+  ``url``, ``html_attr``, or a PHP callback that takes the template "filename"
+  and returns the escaping strategy to use -- the callback cannot be a function
+  name to avoid collision with built-in escaping strategies); set it to
+  ``false`` to disable auto-escaping. The ``name`` escaping strategy determines
+  the escaping strategy to use for a template based on the template filename
+  extension (this strategy does not incur any overhead at runtime as
+  auto-escaping is done at compilation time.)
+
+* ``optimizations`` *integer*
+
+  A flag that indicates which optimizations to apply
+  (default to ``-1`` -- all optimizations are enabled; set it to ``0`` to
+  disable).
+
+Loaders
+-------
+
+Loaders are responsible for loading templates from a resource such as the file
+system.
+
+Compilation Cache
+~~~~~~~~~~~~~~~~~
+
+All template loaders can cache the compiled templates on the filesystem for
+future reuse. It speeds up Twig a lot as templates are only compiled once.
+
+Built-in Loaders
+~~~~~~~~~~~~~~~~
+
+Here is a list of the built-in loaders:
+
+``\Twig\Loader\FilesystemLoader``
+.................................
+
+``\Twig\Loader\FilesystemLoader`` loads templates from the file system. This loader
+can find templates in folders on the file system and is the preferred way to
+load them::
+
+    $loader = new \Twig\Loader\FilesystemLoader($templateDir);
+
+It can also look for templates in an array of directories::
+
+    $loader = new \Twig\Loader\FilesystemLoader([$templateDir1, $templateDir2]);
+
+With such a configuration, Twig will first look for templates in
+``$templateDir1`` and if they do not exist, it will fallback to look for them
+in the ``$templateDir2``.
+
+You can add or prepend paths via the ``addPath()`` and ``prependPath()``
+methods::
+
+    $loader->addPath($templateDir3);
+    $loader->prependPath($templateDir4);
+
+The filesystem loader also supports namespaced templates. This allows to group
+your templates under different namespaces which have their own template paths.
+
+When using the ``setPaths()``, ``addPath()``, and ``prependPath()`` methods,
+specify the namespace as the second argument (when not specified, these
+methods act on the "main" namespace)::
+
+    $loader->addPath($templateDir, 'admin');
+
+Namespaced templates can be accessed via the special
+``@namespace_name/template_path`` notation::
+
+    $twig->render('@admin/index.html', []);
+
+``\Twig\Loader\FilesystemLoader`` support absolute and relative paths. Using relative
+paths is preferred as it makes the cache keys independent of the project root
+directory (for instance, it allows warming the cache from a build server where
+the directory might be different from the one used on production servers)::
+
+    $loader = new \Twig\Loader\FilesystemLoader('templates', getcwd().'/..');
+
+.. note::
+
+    When not passing the root path as a second argument, Twig uses ``getcwd()``
+    for relative paths.
+
+``\Twig\Loader\ArrayLoader``
+............................
+
+``\Twig\Loader\ArrayLoader`` loads a template from a PHP array. It is passed an
+array of strings bound to template names::
+
+    $loader = new \Twig\Loader\ArrayLoader([
+        'index.html' => 'Hello {{ name }}!',
+    ]);
+    $twig = new \Twig\Environment($loader);
+
+    echo $twig->render('index.html', ['name' => 'Fabien']);
+
+This loader is very useful for unit testing. It can also be used for small
+projects where storing all templates in a single PHP file might make sense.
+
+.. tip::
+
+    When using the ``Array`` loader with a cache mechanism, you should know that
+    a new cache key is generated each time a template content "changes" (the
+    cache key being the source code of the template). If you don't want to see
+    your cache grows out of control, you need to take care of clearing the old
+    cache file by yourself.
+
+``\Twig\Loader\ChainLoader``
+............................
+
+``\Twig\Loader\ChainLoader`` delegates the loading of templates to other loaders::
+
+    $loader1 = new \Twig\Loader\ArrayLoader([
+        'base.html' => '{% block content %}{% endblock %}',
+    ]);
+    $loader2 = new \Twig\Loader\ArrayLoader([
+        'index.html' => '{% extends "base.html" %}{% block content %}Hello {{ name }}{% endblock %}',
+        'base.html'  => 'Will never be loaded',
+    ]);
+
+    $loader = new \Twig\Loader\ChainLoader([$loader1, $loader2]);
+
+    $twig = new \Twig\Environment($loader);
+
+When looking for a template, Twig tries each loader in turn and returns as soon
+as the template is found. When rendering the ``index.html`` template from the
+above example, Twig will load it with ``$loader2`` but the ``base.html``
+template will be loaded from ``$loader1``.
+
+.. note::
+
+    You can also add loaders via the ``addLoader()`` method.
+
+Create your own Loader
+~~~~~~~~~~~~~~~~~~~~~~
+
+All loaders implement the ``\Twig\Loader\LoaderInterface``::
+
+    interface \Twig\Loader\LoaderInterface
+    {
+        /**
+         * Returns the source context for a given template logical name.
+         *
+         * @param string $name The template logical name
+         *
+         * @return \Twig\Source
+         *
+         * @throws \Twig\Error\LoaderError When $name is not found
+         */
+        public function getSourceContext($name);
+
+        /**
+         * Gets the cache key to use for the cache for a given template name.
+         *
+         * @param string $name The name of the template to load
+         *
+         * @return string The cache key
+         *
+         * @throws \Twig\Error\LoaderError When $name is not found
+         */
+        public function getCacheKey($name);
+
+        /**
+         * Returns true if the template is still fresh.
+         *
+         * @param string    $name The template name
+         * @param timestamp $time The last modification time of the cached template
+         *
+         * @return bool    true if the template is fresh, false otherwise
+         *
+         * @throws \Twig\Error\LoaderError When $name is not found
+         */
+        public function isFresh($name, $time);
+
+        /**
+         * Check if we have the source code of a template, given its name.
+         *
+         * @param string $name The name of the template to check if we can load
+         *
+         * @return bool    If the template source code is handled by this loader or not
+         */
+        public function exists($name);
+    }
+
+The ``isFresh()`` method must return ``true`` if the current cached template
+is still fresh, given the last modification time, or ``false`` otherwise.
+
+The ``getSourceContext()`` method must return an instance of ``\Twig\Source``.
+
+Using Extensions
+----------------
+
+Twig extensions are packages that add new features to Twig. Register an
+extension via the ``addExtension()`` method::
+
+    $twig->addExtension(new \Twig\Extension\SandboxExtension());
+
+Twig comes bundled with the following extensions:
+
+* *Twig\Extension\CoreExtension*: Defines all the core features of Twig.
+
+* *Twig\Extension\DebugExtension*: Defines the ``dump`` function to help debug
+  template variables.
+
+* *Twig\Extension\EscaperExtension*: Adds automatic output-escaping and the
+  possibility to escape/unescape blocks of code.
+
+* *Twig\Extension\SandboxExtension*: Adds a sandbox mode to the default Twig
+  environment, making it safe to evaluate untrusted code.
+
+* *Twig\Extension\ProfilerExtension*: Enables the built-in Twig profiler.
+
+* *Twig\Extension\OptimizerExtension*: Optimizes the node tree before
+  compilation.
+
+* *Twig\Extension\StringLoaderExtension*: Defines the ``template_from_string``
+   function to allow loading templates from string in a template.
+
+The Core, Escaper, and Optimizer extensions are registered by default.
+
+Built-in Extensions
+-------------------
+
+This section describes the features added by the built-in extensions.
+
+.. tip::
+
+    Read the chapter about :doc:`extending Twig <advanced>` to learn how to
+    create your own extensions.
+
+Core Extension
+~~~~~~~~~~~~~~
+
+The ``core`` extension defines all the core features of Twig:
+
+* :doc:`Tags <tags/index>`;
+* :doc:`Filters <filters/index>`;
+* :doc:`Functions <functions/index>`;
+* :doc:`Tests <tests/index>`.
+
+Escaper Extension
+~~~~~~~~~~~~~~~~~
+
+The ``escaper`` extension adds automatic output escaping to Twig. It defines a
+tag, ``autoescape``, and a filter, ``raw``.
+
+When creating the escaper extension, you can switch on or off the global
+output escaping strategy::
+
+    $escaper = new \Twig\Extension\EscaperExtension('html');
+    $twig->addExtension($escaper);
+
+If set to ``html``, all variables in templates are escaped (using the ``html``
+escaping strategy), except those using the ``raw`` filter:
+
+.. code-block:: twig
+
+    {{ article.to_html|raw }}
+
+You can also change the escaping mode locally by using the ``autoescape`` tag:
+
+.. code-block:: twig
+
+    {% autoescape 'html' %}
+        {{ var }}
+        {{ var|raw }}      {# var won't be escaped #}
+        {{ var|escape }}   {# var won't be double-escaped #}
+    {% endautoescape %}
+
+.. warning::
+
+    The ``autoescape`` tag has no effect on included files.
+
+The escaping rules are implemented as follows:
+
+* Literals (integers, booleans, arrays, ...) used in the template directly as
+  variables or filter arguments are never automatically escaped:
+
+  .. code-block:: html+twig
+
+        {{ "Twig<br/>" }} {# won't be escaped #}
+
+        {% set text = "Twig<br/>" %}
+        {{ text }} {# will be escaped #}
+
+* Expressions which the result is a literal or a variable marked safe
+  are never automatically escaped:
+
+  .. code-block:: html+twig
+
+        {{ foo ? "Twig<br/>" : "<br/>Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br/>" %}
+        {{ true ? text : "<br/>Twig" }} {# will be escaped #}
+        {{ false ? text : "<br/>Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br/>" %}
+        {{ foo ? text|raw : "<br/>Twig" }} {# won't be escaped #}
+
+* Objects with a ``__toString`` method are converted to strings and
+  escaped. You can mark some classes and/or interfaces as being safe for some
+  strategies via ``EscaperExtension::addSafeClass()``:
+
+  .. code-block:: twig
+
+        // mark object of class Foo as safe for the HTML strategy
+        $escaper->addSafeClass('Foo', ['html']);
+
+        // mark object of interface Foo as safe for the HTML strategy
+        $escaper->addSafeClass('FooInterface', ['html']);
+
+        // mark object of class Foo as safe for the HTML and JS strategies
+        $escaper->addSafeClass('Foo', ['html', 'js']);
+
+        // mark object of class Foo as safe for all strategies
+        $escaper->addSafeClass('Foo', ['all']);
+
+* Escaping is applied before printing, after any other filter is applied:
+
+  .. code-block:: twig
+
+        {{ var|upper }} {# is equivalent to {{ var|upper|escape }} #}
+
+* The `raw` filter should only be used at the end of the filter chain:
+
+  .. code-block:: twig
+
+        {{ var|raw|upper }} {# will be escaped #}
+
+        {{ var|upper|raw }} {# won't be escaped #}
+
+* Automatic escaping is not applied if the last filter in the chain is marked
+  safe for the current context (e.g. ``html`` or ``js``). ``escape`` and
+  ``escape('html')`` are marked safe for HTML, ``escape('js')`` is marked
+  safe for JavaScript, ``raw`` is marked safe for everything.
+
+  .. code-block:: twig
+
+        {% autoescape 'js' %}
+            {{ var|escape('html') }} {# will be escaped for HTML and JavaScript #}
+            {{ var }} {# will be escaped for JavaScript #}
+            {{ var|escape('js') }} {# won't be double-escaped #}
+        {% endautoescape %}
+
+.. note::
+
+    Note that autoescaping has some limitations as escaping is applied on
+    expressions after evaluation. For instance, when working with
+    concatenation, ``{{ foo|raw ~ bar }}`` won't give the expected result as
+    escaping is applied on the result of the concatenation, not on the
+    individual variables (so, the ``raw`` filter won't have any effect here).
+
+Sandbox Extension
+~~~~~~~~~~~~~~~~~
+
+The ``sandbox`` extension can be used to evaluate untrusted code. Access to
+unsafe attributes and methods is prohibited. The sandbox security is managed
+by a policy instance. By default, Twig comes with one policy class:
+``\Twig\Sandbox\SecurityPolicy``. This class allows you to white-list some
+tags, filters, properties, and methods::
+
+    $tags = ['if'];
+    $filters = ['upper'];
+    $methods = [
+        'Article' => ['getTitle', 'getBody'],
+    ];
+    $properties = [
+        'Article' => ['title', 'body'],
+    ];
+    $functions = ['range'];
+    $policy = new \Twig\Sandbox\SecurityPolicy($tags, $filters, $methods, $properties, $functions);
+
+With the previous configuration, the security policy will only allow usage of
+the ``if`` tag, and the ``upper`` filter. Moreover, the templates will only be
+able to call the ``getTitle()`` and ``getBody()`` methods on ``Article``
+objects, and the ``title`` and ``body`` public properties. Everything else
+won't be allowed and will generate a ``\Twig\Sandbox\SecurityError`` exception.
+
+The policy object is the first argument of the sandbox constructor::
+
+    $sandbox = new \Twig\Extension\SandboxExtension($policy);
+    $twig->addExtension($sandbox);
+
+By default, the sandbox mode is disabled and should be enabled when including
+untrusted template code by using the ``sandbox`` tag:
+
+.. code-block:: twig
+
+    {% sandbox %}
+        {% include 'user.html' %}
+    {% endsandbox %}
+
+You can sandbox all templates by passing ``true`` as the second argument of
+the extension constructor::
+
+    $sandbox = new \Twig\Extension\SandboxExtension($policy, true);
+
+Profiler Extension
+~~~~~~~~~~~~~~~~~~
+
+The ``profiler`` extension enables a profiler for Twig templates; it should
+only be used on your development machines as it adds some overhead::
+
+    $profile = new \Twig\Profiler\Profile();
+    $twig->addExtension(new \Twig\Extension\ProfilerExtension($profile));
+
+    $dumper = new \Twig\Profiler\Dumper\TextDumper();
+    echo $dumper->dump($profile);
+
+A profile contains information about time and memory consumption for template,
+block, and macro executions.
+
+You can also dump the data in a `Blackfire.io <https://blackfire.io/>`_
+compatible format::
+
+    $dumper = new \Twig\Profiler\Dumper\BlackfireDumper();
+    file_put_contents('/path/to/profile.prof', $dumper->dump($profile));
+
+Upload the profile to visualize it (create a `free account
+<https://blackfire.io/signup?utm_source=twig&utm_medium=doc&utm_campaign=profiler>`_
+first):
+
+.. code-block:: sh
+
+    blackfire --slot=7 upload /path/to/profile.prof
+
+Optimizer Extension
+~~~~~~~~~~~~~~~~~~~
+
+The ``optimizer`` extension optimizes the node tree before compilation::
+
+    $twig->addExtension(new \Twig\Extension\OptimizerExtension());
+
+By default, all optimizations are turned on. You can select the ones you want
+to enable by passing them to the constructor::
+
+    $optimizer = new \Twig\Extension\OptimizerExtension(\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_FOR);
+
+    $twig->addExtension($optimizer);
+
+Twig supports the following optimizations:
+
+* ``\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_ALL``, enables all optimizations
+  (this is the default value).
+
+* ``\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_NONE``, disables all optimizations.
+  This reduces the compilation time, but it can increase the execution time
+  and the consumed memory.
+
+* ``\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_FOR``, optimizes the ``for`` tag by
+  removing the ``loop`` variable creation whenever possible.
+
+* ``\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_RAW_FILTER``, removes the ``raw``
+  filter whenever possible.
+
+* ``\Twig\NodeVisitor\OptimizerNodeVisitor::OPTIMIZE_VAR_ACCESS``, simplifies the creation
+  and access of variables in the compiled templates whenever possible.
+
+Exceptions
+----------
+
+Twig can throw exceptions:
+
+* ``\Twig\Error\Error``: The base exception for all errors.
+
+* ``\Twig\Error\SyntaxError``: Thrown to tell the user that there is a problem with
+  the template syntax.
+
+* ``\Twig\Error\RuntimeError``: Thrown when an error occurs at runtime (when a filter
+  does not exist for instance).
+
+* ``\Twig\Error\LoaderError``: Thrown when an error occurs during template loading.
+
+* ``\Twig\Sandbox\SecurityError``: Thrown when an unallowed tag, filter, or
+  method is called in a sandboxed template.

+Coding Standards
+================
+
+When writing Twig templates, we recommend you to follow these official coding
+standards:
+
+* Put one (and only one) space after the start of a delimiter (``{{``, ``{%``,
+  and ``{#``) and before the end of a delimiter (``}}``, ``%}``, and ``#}``):
+
+  .. code-block:: twig
+
+    {{ foo }}
+    {# comment #}
+    {% if foo %}{% endif %}
+
+  When using the whitespace control character, do not put any spaces between
+  it and the delimiter:
+
+  .. code-block:: twig
+
+    {{- foo -}}
+    {#- comment -#}
+    {%- if foo -%}{%- endif -%}
+
+* Put one (and only one) space before and after the following operators:
+  comparison operators (``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``), math
+  operators (``+``, ``-``, ``/``, ``*``, ``%``, ``//``, ``**``), logic
+  operators (``not``, ``and``, ``or``), ``~``, ``is``, ``in``, and the ternary
+  operator (``?:``):
+
+  .. code-block:: twig
+
+     {{ 1 + 2 }}
+     {{ foo ~ bar }}
+     {{ true ? true : false }}
+
+* Put one (and only one) space after the ``:`` sign in hashes and ``,`` in
+  arrays and hashes:
+
+  .. code-block:: twig
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Do not put any spaces after an opening parenthesis and before a closing
+  parenthesis in expressions:
+
+  .. code-block:: twig
+
+    {{ 1 + (2 * 3) }}
+
+* Do not put any spaces before and after string delimiters:
+
+  .. code-block:: twig
+
+    {{ 'foo' }}
+    {{ "foo" }}
+
+* Do not put any spaces before and after the following operators: ``|``,
+  ``.``, ``..``, ``[]``:
+
+  .. code-block:: twig
+
+    {{ foo|upper|lower }}
+    {{ user.name }}
+    {{ user[name] }}
+    {% for i in 1..12 %}{% endfor %}
+
+* Do not put any spaces before and after the parenthesis used for filter and
+  function calls:
+
+  .. code-block:: twig
+
+     {{ foo|default('foo') }}
+     {{ range(1..10) }}
+
+* Do not put any spaces before and after the opening and the closing of arrays
+  and hashes:
+
+  .. code-block:: twig
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Use lower cased and underscored variable names:
+
+  .. code-block:: twig
+
+     {% set foo = 'foo' %}
+     {% set foo_bar = 'foo' %}
+
+* Indent your code inside tags (use the same indentation as the one used for
+  the target language of the rendered template):
+
+  .. code-block:: twig
+
+     {% block foo %}
+         {% if true %}
+             true
+         {% endif %}
+     {% endblock %}

+``date``
+========
+
+The ``date`` filter formats a date to a given format:
+
+.. code-block:: twig
+
+    {{ post.published_at|date("m/d/Y") }}
+
+The format specifier is the same as supported by `date`_,
+except when the filtered data is of type `DateInterval`_, when the format must conform to
+`DateInterval::format`_ instead.
+
+The ``date`` filter accepts strings (it must be in a format supported by the
+`strtotime`_ function), `DateTime`_ instances, or `DateInterval`_ instances. For
+instance, to display the current date, filter the word "now":
+
+.. code-block:: twig
+
+    {{ "now"|date("m/d/Y") }}
+
+To escape words and characters in the date format use ``\\`` in front of each
+character:
+
+.. code-block:: twig
+
+    {{ post.published_at|date("F jS \\a\\t g:ia") }}
+
+If the value passed to the ``date`` filter is ``null``, it will return the
+current date by default. If an empty string is desired instead of the current
+date, use a ternary operator:
+
+.. code-block:: twig
+
+    {{ post.published_at is empty ? "" : post.published_at|date("m/d/Y") }}
+
+If no format is provided, Twig will use the default one: ``F j, Y H:i``. This
+default can be changed by calling the ``setDateFormat()`` method on the
+``core`` extension instance. The first argument is the default format for
+dates and the second one is the default format for date intervals::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->getExtension(\Twig\Extension\CoreExtension::class)->setDateFormat('d/m/Y', '%d days');
+
+Timezone
+--------
+
+By default, the date is displayed by applying the default timezone (the one
+specified in php.ini or declared in Twig -- see below), but you can override
+it by explicitly specifying a timezone:
+
+.. code-block:: twig
+
+    {{ post.published_at|date("m/d/Y", "Europe/Paris") }}
+
+If the date is already a DateTime object, and if you want to keep its current
+timezone, pass ``false`` as the timezone value:
+
+.. code-block:: twig
+
+    {{ post.published_at|date("m/d/Y", false) }}
+
+The default timezone can also be set globally by calling ``setTimezone()``::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->getExtension(\Twig\Extension\CoreExtension::class)->setTimezone('Europe/Paris');

+``default``
+===========
+
+The ``default`` filter returns the passed default value if the value is
+undefined or empty, otherwise the value of the variable:
+
+.. code-block:: twig
+
+    {{ var|default('var is not defined') }}
+
+    {{ var.foo|default('foo item on var is not defined') }}
+
+    {{ var['foo']|default('foo item on var is not defined') }}
+
+    {{ ''|default('passed var is empty')  }}
+
+When using the ``default`` filter on an expression that uses variables in some
+method calls, be sure to use the ``default`` filter whenever a variable can be
+undefined:
+
+.. code-block:: twig
+
+    {{ var.method(foo|default('foo'))|default('foo') }}
+    
+Using the ``default`` filter on a boolean variable might trigger unexpected behavior, as
+``false`` is treated as an empty value. Consider using ``??`` instead:
+
+.. code-block:: twig
+
+    {% set foo = false %}
+    {{ foo|default(true) }} {# true #}
+    {{ foo ?? true }} {# false #}

+``escape``
+==========
+
+The ``escape`` filter escapes a string using strategies that depend on the
+context.
+
+By default, it uses the HTML escaping strategy:
+
+.. code-block:: html+twig
+
+    <p>
+        {{ user.username|escape }}
+    </p>
+
+For convenience, the ``e`` filter is defined as an alias:
+
+.. code-block:: html+twig
+
+    <p>
+        {{ user.username|e }}
+    </p>
+
+The ``escape`` filter can also be used in other contexts than HTML thanks to
+an optional argument which defines the escaping strategy to use:
+
+.. code-block:: twig
+
+    {{ user.username|e }}
+    {# is equivalent to #}
+    {{ user.username|e('html') }}
+
+And here is how to escape variables included in JavaScript code:
+
+.. code-block:: twig
+
+    {{ user.username|escape('js') }}
+    {{ user.username|e('js') }}
+
+The ``escape`` filter supports the following escaping strategies for HTML
+documents:
+
+* ``html``: escapes a string for the **HTML body** context.
+
+* ``js``: escapes a string for the **JavaScript** context.
+
+* ``css``: escapes a string for the **CSS** context. CSS escaping can be
+  applied to any string being inserted into CSS and escapes everything except
+  alphanumerics.
+
+* ``url``: escapes a string for the **URI or parameter** contexts. This should
+  not be used to escape an entire URI; only a subcomponent being inserted.
+
+* ``html_attr``: escapes a string for the **HTML attribute** context.
+
+Note that doing contextual escaping in HTML documents is hard and choosing the
+right escaping strategy depends on a lot of factors. Please, read related
+documentation like `the OWASP prevention cheat sheet
+<https://github.com/OWASP/CheatSheetSeries/blob/master/cheatsheets/Cross_Site_Scripting_Prevention_Cheat_Sheet.md>`_
+to learn more about this topic.
+
+.. note::
+
+    Internally, ``escape`` uses the PHP native `htmlspecialchars`_ function
+    for the HTML escaping strategy.
+
+.. caution::
+
+    When using automatic escaping, Twig tries to not double-escape a variable
+    when the automatic escaping strategy is the same as the one applied by the
+    escape filter; but that does not work when using a variable as the
+    escaping strategy:
+
+    .. code-block:: twig
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape('html') }}   {# won't be double-escaped #}
+            {{ var|escape(strategy) }} {# will be double-escaped #}
+        {% endautoescape %}
+
+    When using a variable as the escaping strategy, you should disable
+    automatic escaping:
+
+    .. code-block:: twig
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape(strategy)|raw }} {# won't be double-escaped #}
+        {% endautoescape %}
+
+Custom Escapers
+---------------
+
+You can define custom escapers by calling the ``setEscaper()`` method on the
+escaper extension instance. The first argument is the escaper name (to be
+used in the ``escape`` call) and the second one must be a valid PHP callable::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->getExtension(\Twig\Extension\EscaperExtension::class)->setEscaper('csv', 'csv_escaper');
+
+When called by Twig, the callable receives the Twig environment instance, the
+string to escape, and the charset.
+
+.. note::
+
+    Built-in escapers cannot be overridden mainly because they should be
+    considered as the final implementation and also for better performance.
+
+Arguments
+---------
+
+* ``strategy``: The escaping strategy
+* ``charset``:  The string charset

+``filter``
+==========
+
+The ``filter`` filter filters elements of a sequence or a mapping using an arrow

+
+    {{ sizes|filter(v => v > 38)|join(', ') }}

+.. code-block:: twig
+
+    {% for v in sizes|filter(v => v > 38) -%}
+        {{ v }}
+    {% endfor %}

+        s:  36,

+        {{ k }} = {{ v }}
+    {% endfor %}
+    {# output l = 40 xl = 42 #}
+
+The arrow function also receives the key as a second argument:

+

+``format_number``
+=================
+
+The ``format_number`` filter formats a number:
+
+.. code-block:: twig
+
+    {{ '12.345'|format_number }}
+
+You can pass attributes to tweak the output:
+
+.. code-block:: twig
+
+    {# 12.34 #}
+    {{ '12.345'|format_number({rounding_mode: 'floor'}) }}
+
+    {# 1000000.0000 #}
+    {{ '1000000'|format_number({fraction_digit: 4}) }}
+
+The list of supported options:
+
+* ``grouping_used``;
+* ``decimal_always_shown``;
+* ``max_integer_digit``;
+* ``min_integer_digit``;
+* ``integer_digit``;
+* ``max_fraction_digit``;
+* ``min_fraction_digit``;
+* ``fraction_digit``;
+* ``multiplier``;
+* ``grouping_size``;
+* ``rounding_mode``;
+* ``rounding_increment``;
+* ``format_width``;
+* ``padding_position``;
+* ``secondary_grouping_size``;
+* ``significant_digits_used``;
+* ``min_significant_digits_used``;
+* ``max_significant_digits_used``;
+* ``lenient_parse``.
+
+Besides plain numbers, the filter can also format numbers in various styles:
+
+.. code-block:: twig
+
+    {# 1,234% #}
+    {{ '12.345'|format_number(style='percent') }}
+
+    {# twelve point three four five #}
+    {{ '12.345'|format_number(style='spellout') }}
+
+    {# 12 sec. #}
+    {{ '12'|format_duration_number }}
+
+The list of supported styles:
+
+* ``decimal``;
+* ``currency``;
+* ``percent``;
+* ``scientific``;
+* ``spellout``;
+* ``ordinal``;
+* ``duration``.
+
+As a shortcut, you can use the ``format_*_number`` filters by replacing `*` with
+a style:
+
+.. code-block:: twig
+
+    {# 1,234% #}
+    {{ '12.345'|format_percent_number }}
+
+    {# twelve point three four five #}
+    {{ '12.345'|format_spellout_number }}
+
+You can pass attributes to tweak the output:
+
+.. code-block:: twig
+
+    {# 12.3% #}
+    {{ '0.12345'|format_percent_number({rounding_mode: 'floor', fraction_digit: 1}) }}
+
+By default, the filter uses the current locale. You can pass it explicitly:
+
+.. code-block:: twig
+

+``html_to_markdown``
+====================
+
+The ``html_to_markdown`` filter converts a block of HTML to Markdown:
+
+.. code-block:: html+twig
+
+    {% apply html_to_markdown %}
+        <html>
+            <h1>Hello!</h1>
+        </html>
+    {% endapply %}
+
+You can also use the filter on an entire template which you ``include``:
+
+.. code-block:: twig
+
+    {{ include('some_template.html.twig')|html_to_markdown }}
+
+.. note::
+
+    The ``html_to_markdown`` filter is part of the ``MarkdownExtension`` which
+    is not installed by default. Install it first:
+
+    .. code-block:: bash
+
+        $ composer require twig/markdown-extra
+
+    On Symfony projects, you can automatically enable it by installing the
+    ``twig/extra-bundle``:
+
+    .. code-block:: bash
+
+        $ composer require twig/extra-bundle
+
+    Or add the extension explicitly on the Twig environment::
+
+        use Twig\Extra\Markdown\MarkdownExtension;
+
+        $twig = new \Twig\Environment(...);
+        $twig->addExtension(new MarkdownExtension());
+
+    If you are not using Symfony, you must also register the extension runtime::
+
+        use Twig\Extra\Markdown\DefaultMarkdown;
+        use Twig\Extra\Markdown\MarkdownRuntime;
+        use Twig\RuntimeLoader\RuntimeLoaderInterface;
+
+        $twig->addRuntimeLoader(new class implements RuntimeLoaderInterface {
+            public function load($class) {
+                if (MarkdownRuntime::class === $class) {
+                    return new MarkdownRuntime(new DefaultMarkdown());
+                }
+            }
+        });
+
+``html_to_markdown`` is just a frontend; the actual conversion is done by one of
+the following compatible libraries, from which you can choose:
+
+* `league/html-to-markdown`_
+* `michelf/php-markdown`_
+* `erusev/parsedown`_
+
+Depending on the library, you can also add some options by passing them as an argument
+to the filter. Example for ``league/html-to-markdown``:
+
+.. code-block:: html+twig
+
+    {% apply html_to_markdown({hard_break: false}) %}
+        <html>
+            <h1>Hello!</h1>
+        </html>

+.. code-block:: twig
+
+    {% apply markdown_to_html %}
+    Title
+    ======
+
+    Hello!
+    {% endapply %}
+
+Note that you can indent the Markdown content as leading whitespaces will be
+removed consistently before conversion:
+
+.. code-block:: twig
+
+    {% apply markdown_to_html %}
+        Title
+        ======
+
+        Hello!
+    {% endapply %}
+
+You can also use the filter on an included file or a variable:
+
+.. code-block:: twig
+
+    {{ include('some_template.markdown.twig')|markdown_to_html }}
+    
+    {{ changelog|markdown_to_html }}
+
+.. note::
+
+    The ``markdown_to_html`` filter is part of the ``MarkdownExtension`` which
+    is not installed by default. Install it first:
+
+    .. code-block:: bash
+
+        $ composer require twig/markdown-extra
+
+    Then, on Symfony projects, install the ``twig/extra-bundle``:
+
+    .. code-block:: bash
+
+        $ composer require twig/extra-bundle
+
+    Otherwise, add the extension explicitly on the Twig environment::
+
+        use Twig\Extra\Markdown\MarkdownExtension;
+
+        $twig = new \Twig\Environment(...);
+        $twig->addExtension(new MarkdownExtension());
+
+    If you are not using Symfony, you must also register the extension runtime::
+
+        use Twig\Extra\Markdown\DefaultMarkdown;
+        use Twig\Extra\Markdown\MarkdownRuntime;
+        use Twig\RuntimeLoader\RuntimeLoaderInterface;
+
+        $twig->addRuntimeLoader(new class implements RuntimeLoaderInterface {
+            public function load($class) {
+                if (MarkdownRuntime::class === $class) {
+                    return new MarkdownRuntime(new DefaultMarkdown());
+                }
+            }
+        });
+       
+    Afterwards you need to install a markdown library of your choice. Some of them are
+    mentioned in the ``require-dev`` section of the ``twig/markdown-extra`` package.

+``number_format``
+=================
+
+The ``number_format`` filter formats numbers.  It is a wrapper around PHP's
+`number_format`_ function:
+
+.. code-block:: twig
+
+    {{ 200.35|number_format }}
+
+You can control the number of decimal places, decimal point, and thousands
+separator using the additional arguments:
+
+.. code-block:: twig
+
+    {{ 9800.333|number_format(2, '.', ',') }}
+
+To format negative numbers or math calculation, wrap the previous statement
+with parentheses (needed because of Twig's :ref:`precedence of operators
+<twig-expressions>`):
+
+.. code-block:: twig
+
+    {{ -9800.333|number_format(2, '.', ',') }} {# outputs : -9 #}
+    {{ (-9800.333)|number_format(2, '.', ',') }} {# outputs : -9,800.33 #}
+    {{  1 + 0.2|number_format(2) }} {# outputs : 1.2 #}
+    {{ (1 + 0.2)|number_format(2) }} {# outputs : 1.20 #}
+
+If no formatting options are provided then Twig will use the default formatting
+options of:
+
+* 0 decimal places.
+* ``.`` as the decimal point.
+* ``,`` as the thousands separator.
+
+These defaults can be changed through the core extension::
+
+    $twig = new \Twig\Environment($loader);
+    $twig->getExtension(\Twig\Extension\CoreExtension::class)->setNumberFormat(3, '.', ',');
+
+The defaults set for ``number_format`` can be over-ridden upon each call using the
+additional parameters.
+
+Arguments
+---------
+
+* ``decimal``:       The number of decimal points to display
+* ``decimal_point``: The character(s) to use for the decimal point

+
+    {% for i in [1, 2, 3, 4, 5]|slice(start, length) %}
+        {# ... #}

+
+If the start is non-negative, the sequence will start at that start in the
+variable. If start is negative, the sequence will start that far from the end
+of the variable.
+
+If length is given and is positive, then the sequence will have up to that
+many elements in it. If the variable is shorter than the length, then only the
+available variable elements will be present. If length is given and is
+negative then the sequence will stop that many elements from the end of the
+variable. If it is omitted, then the sequence will have everything from offset
+up until the end of the variable.

+``spaceless``
+=============
+
+Use the ``spaceless`` filter to remove whitespace *between HTML tags*, not
+whitespace within HTML tags or whitespace in plain text:
+
+.. code-block:: html+twig
+
+    {{
+        "<div>
+            <strong>foo</strong>
+        </div>
+        "|spaceless }}
+
+    {# output will be <div><strong>foo</strong></div> #}
+
+You can combine ``spaceless`` with the ``apply`` tag to apply the transformation
+on large amounts of HTML:
+
+.. code-block:: html+twig
+
+    {% apply spaceless %}
+        <div>
+            <strong>foo</strong>
+        </div>
+    {% endapply %}
+
+    {# output will be <div><strong>foo</strong></div> #}
+
+This tag is not meant to "optimize" the size of the generated HTML content but
+merely to avoid extra whitespace between HTML tags to avoid browser rendering
+quirks under some circumstances.
+
+.. caution::
+
+    As the filter uses a regular expression behind the scenes, its performance
+    is directly related to the text size you are working on (remember that
+    filters are executed at runtime).
+
+.. tip::
+
+    If you want to optimize the size of the generated HTML content, gzip
+    compress the output instead.
+
+.. tip::
+
+    If you want to create a tag that actually removes all extra whitespace in
+    an HTML string, be warned that this is not as easy as it seems to be
+    (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
+    library like Tidy is probably a better idea.
+
+.. tip::
+
+    For more information on whitespace control, read the

+``split``
+=========
+
+The ``split`` filter splits a string by the given delimiter and returns a list
+of strings:
+
+.. code-block:: twig
+
+    {% set foo = "one,two,three"|split(',') %}
+    {# foo contains ['one', 'two', 'three'] #}
+
+You can also pass a ``limit`` argument:
+
+* If ``limit`` is positive, the returned array will contain a maximum of
+  limit elements with the last element containing the rest of string;
+
+* If ``limit`` is negative, all components except the last -limit are
+  returned;
+
+* If ``limit`` is zero, then this is treated as 1.
+
+.. code-block:: twig
+
+    {% set foo = "one,two,three,four,five"|split(',', 3) %}
+    {# foo contains ['one', 'two', 'three,four,five'] #}
+
+If the ``delimiter`` is an empty string, then value will be split by equal
+chunks. Length is set by the ``limit`` argument (one character by default).
+
+.. code-block:: twig
+
+    {% set foo = "123"|split('') %}
+    {# foo contains ['1', '2', '3'] #}
+
+    {% set bar = "aabbcc"|split('', 2) %}
+    {# bar contains ['aa', 'bb', 'cc'] #}
+
+.. note::
+
+    Internally, Twig uses the PHP `explode`_ or `str_split`_ (if delimiter is
+    empty) functions for string splitting.

+``u``
+=====
+
+The ``u`` filter wraps a text in a Unicode object (a `Symfony UnicodeString
+instance <https://symfony.com/doc/current/components/string.html>`_) that
+exposes methods to "manipulate" the string.
+
+Let's see some common use cases.
+
+Wrapping a text to a given number of characters:
+
+.. code-block:: twig
+
+    {{ 'Symfony String + Twig = <3'|u.wordwrap(5) }}
+    Symfony
+    String
+    +
+    Twig
+    = <3
+
+Truncating a string:
+
+.. code-block:: twig
+
+    {{ 'Lorem ipsum'|u.truncate(8) }}
+    Lorem ip
+
+    {{ 'Lorem ipsum'|u.truncate(8, '...') }}
+    Lorem...
+
+The ``truncate`` method also accepts a third argument to preserve whole words:
+
+.. code-block:: twig
+
+    {{ 'Lorem ipsum dolor'|u.truncate(10, '...', false) }}
+    Lorem ipsum...
+
+Converting a string to *snake* case or *camelCase*:
+
+.. code-block:: twig
+
+    {{ 'SymfonyStringWithTwig'|u.snake }}
+    symfony_string_with_twig
+
+    {{ 'symfony_string with twig'|u.camel.title }}
+    SymfonyStringWithTwig
+
+You can also chain methods:
+
+.. code-block:: twig
+
+    {{ 'Symfony String + Twig = <3'|u.wordwrap(5).upper }}
+    SYMFONY
+    STRING
+    +
+    TWIG
+    = <3
+
+For large strings manipulation, use the ``apply`` tag:
+
+.. code-block:: twig
+
+    {% apply u.wordwrap(5) %}
+        Some large amount of text...
+    {% endapply %}

+``dump``
+========
+
+The ``dump`` function dumps information about a template variable. This is
+mostly useful to debug a template that does not behave as expected by
+introspecting its variables:
+
+.. code-block:: twig
+
+    {{ dump(user) }}
+
+.. note::
+
+    The ``dump`` function is not available by default. You must add the
+    ``\Twig\Extension\DebugExtension`` extension explicitly when creating your Twig
+    environment::
+
+        $twig = new \Twig\Environment($loader, [
+            'debug' => true,
+            // ...
+        ]);
+        $twig->addExtension(new \Twig\Extension\DebugExtension());
+
+    Even when enabled, the ``dump`` function won't display anything if the
+    ``debug`` option on the environment is not enabled (to avoid leaking debug
+    information on a production server).
+
+In an HTML context, wrap the output with a ``pre`` tag to make it easier to
+read:
+
+.. code-block:: html+twig
+
+    <pre>
+        {{ dump(user) }}
+    </pre>
+
+.. tip::
+
+    Using a ``pre`` tag is not needed when `XDebug`_ is enabled and
+    ``html_errors`` is ``on``; as a bonus, the output is also nicer with
+    XDebug enabled.
+
+You can debug several variables by passing them as additional arguments:
+
+.. code-block:: twig
+
+    {{ dump(user, categories) }}
+
+If you don't pass any value, all variables from the current context are

+``include``
+===========
+
+The ``include`` function returns the rendered content of a template:
+
+.. code-block:: twig
+
+    {{ include('template.html') }}
+    {{ include(some_var) }}
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+The context is passed by default to the template but you can also pass
+additional variables:
+
+.. code-block:: twig
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {{ include('template.html', {foo: 'bar'}) }}
+
+You can disable access to the context by setting ``with_context`` to
+``false``:
+
+.. code-block:: twig
+
+    {# only the foo variable will be accessible #}
+    {{ include('template.html', {foo: 'bar'}, with_context = false) }}
+
+.. code-block:: twig
+
+    {# no variables will be accessible #}
+    {{ include('template.html', with_context = false) }}
+
+And if the expression evaluates to a ``\Twig\Template`` or a
+``\Twig\TemplateWrapper`` instance, Twig will use it directly::
+
+    // {{ include(template) }}
+
+    $template = $twig->load('some_template.twig');
+
+    $twig->display('template.twig', ['template' => $template]);
+
+When you set the ``ignore_missing`` flag, Twig will return an empty string if
+the template does not exist:
+
+.. code-block:: twig
+
+    {{ include('sidebar.html', ignore_missing = true) }}
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be rendered:
+
+.. code-block:: twig
+
+    {{ include(['page_detailed.html', 'page.html']) }}
+
+If ``ignore_missing`` is set, it will fall back to rendering nothing if none

+Twig Internals
+==============
+
+Twig is very extensible and you can hack it. Keep in mind that you
+should probably try to create an extension before hacking the core, as most
+features and enhancements can be handled with extensions. This chapter is also
+useful for people who want to understand how Twig works under the hood.
+
+How does Twig work?
+-------------------
+
+The rendering of a Twig template can be summarized into four key steps:
+
+* **Load** the template: If the template is already compiled, load it and go
+  to the *evaluation* step, otherwise:
+
+  * First, the **lexer** tokenizes the template source code into small pieces
+    for easier processing;
+
+  * Then, the **parser** converts the token stream into a meaningful tree
+    of nodes (the Abstract Syntax Tree);
+
+  * Finally, the *compiler* transforms the AST into PHP code.
+
+* **Evaluate** the template: It means calling the ``display()``
+  method of the compiled template and passing it the context.
+
+The Lexer
+---------
+
+The lexer tokenizes a template source code into a token stream (each token is
+an instance of ``\Twig\Token``, and the stream is an instance of
+``\Twig\TokenStream``). The default lexer recognizes 13 different token types:
+
+* ``\Twig\Token::BLOCK_START_TYPE``, ``\Twig\Token::BLOCK_END_TYPE``: Delimiters for blocks (``{% %}``)
+* ``\Twig\Token::VAR_START_TYPE``, ``\Twig\Token::VAR_END_TYPE``: Delimiters for variables (``{{ }}``)
+* ``\Twig\Token::TEXT_TYPE``: A text outside an expression;
+* ``\Twig\Token::NAME_TYPE``: A name in an expression;
+* ``\Twig\Token::NUMBER_TYPE``: A number in an expression;
+* ``\Twig\Token::STRING_TYPE``: A string in an expression;
+* ``\Twig\Token::OPERATOR_TYPE``: An operator;
+* ``\Twig\Token::PUNCTUATION_TYPE``: A punctuation sign;
+* ``\Twig\Token::INTERPOLATION_START_TYPE``, ``\Twig\Token::INTERPOLATION_END_TYPE``: Delimiters for string interpolation;
+* ``\Twig\Token::EOF_TYPE``: Ends of template.
+
+You can manually convert a source code into a token stream by calling the
+``tokenize()`` method of an environment::
+
+    $stream = $twig->tokenize(new \Twig\Source($source, $identifier));
+
+As the stream has a ``__toString()`` method, you can have a textual
+representation of it by echoing the object::
+
+    echo $stream."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    TEXT_TYPE(Hello )
+    VAR_START_TYPE()
+    NAME_TYPE(name)
+    VAR_END_TYPE()
+    EOF_TYPE()
+
+.. note::
+
+    The default lexer (``\Twig\Lexer``) can be changed by calling
+    the ``setLexer()`` method::
+
+        $twig->setLexer($lexer);
+
+The Parser
+----------
+
+The parser converts the token stream into an AST (Abstract Syntax Tree), or a
+node tree (an instance of ``\Twig\Node\ModuleNode``). The core extension defines
+the basic nodes like: ``for``, ``if``, ... and the expression nodes.
+
+You can manually convert a token stream into a node tree by calling the
+``parse()`` method of an environment::
+
+    $nodes = $twig->parse($stream);
+
+Echoing the node object gives you a nice representation of the tree::
+
+    echo $nodes."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    \Twig\Node\ModuleNode(
+      \Twig\Node\TextNode(Hello )
+      \Twig\Node\PrintNode(
+        \Twig\Node\Expression\NameExpression(name)
+      )
+    )
+
+.. note::
+
+    The default parser (``\Twig\TokenParser\AbstractTokenParser``) can be changed by calling the
+    ``setParser()`` method::
+
+        $twig->setParser($parser);
+
+The Compiler
+------------
+
+The last step is done by the compiler. It takes a node tree as an input and
+generates PHP code usable for runtime execution of the template.
+
+You can manually compile a node tree to PHP code with the ``compile()`` method
+of an environment::
+
+    $php = $twig->compile($nodes);
+
+The generated template for a ``Hello {{ name }}`` template reads as follows
+(the actual output can differ depending on the version of Twig you are
+using)::
+
+    /* Hello {{ name }} */
+    class __TwigTemplate_1121b6f109fe93ebe8c6e22e3712bceb extends Template
+    {
+        protected function doDisplay(array $context, array $blocks = [])
+        {
+            // line 1
+            echo "Hello ";
+            echo twig_escape_filter($this->env, (isset($context["name"]) ? $context["name"] : null), "html", null, true);
+        }
+
+        // some more code
+    }
+
+.. note::
+
+    The default compiler (``\Twig\Compiler``) can be changed by calling the
+    ``setCompiler()`` method::
+
+        $twig->setCompiler($compiler);

+Introduction
+============
+
+Welcome to the documentation for Twig, the flexible, fast, and secure template
+engine for PHP.
+
+Twig is both designer and developer friendly by sticking to PHP's principles and
+adding functionality useful for templating environments.
+
+The key-features are...
+
+* *Fast*: Twig compiles templates down to plain optimized PHP code. The
+  overhead compared to regular PHP code was reduced to the very minimum.
+
+* *Secure*: Twig has a sandbox mode to evaluate untrusted template code. This
+  allows Twig to be used as a template language for applications where users
+  may modify the template design.
+
+* *Flexible*: Twig is powered by a flexible lexer and parser. This allows the
+  developer to define their own custom tags and filters, and to create their own DSL.
+
+Twig is used by many Open-Source projects like Symfony, Drupal8, eZPublish,
+phpBB, Matomo, OroCRM; and many frameworks have support for it as well like
+Slim, Yii, Laravel, and Codeigniter — just to name a few.
+
+.. admonition:: Screencast

+    Like to learn from video tutorials? Check out the `SymfonyCasts Twig Tutorial`_!
+
+Prerequisites
+-------------
+
+Twig 3.x needs at least **PHP 7.2.5** to run.
+
+Installation
+------------
+
+The recommended way to install Twig is via Composer:
+
+.. code-block:: bash
+
+    composer require "twig/twig:^3.0"
+
+Basic API Usage
+---------------
+
+This section gives you a brief introduction to the PHP API for Twig::
+
+    require_once '/path/to/vendor/autoload.php';
+
+    $loader = new \Twig\Loader\ArrayLoader([
+        'index' => 'Hello {{ name }}!',
+    ]);
+    $twig = new \Twig\Environment($loader);
+
+    echo $twig->render('index', ['name' => 'Fabien']);
+
+Twig uses a loader (``\Twig\Loader\ArrayLoader``) to locate templates, and an
+environment (``\Twig\Environment``) to store its configuration.
+
+The ``render()`` method loads the template passed as a first argument and
+renders it with the variables passed as a second argument.
+
+As templates are generally stored on the filesystem, Twig also comes with a
+filesystem loader::
+
+    $loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
+    $twig = new \Twig\Environment($loader, [
+        'cache' => '/path/to/compilation_cache',
+    ]);
+
+    echo $twig->render('index.html', ['name' => 'Fabien']);

+Recipes
+=======
+
+.. _deprecation-notices:
+
+Displaying Deprecation Notices
+------------------------------
+
+Deprecated features generate deprecation notices (via a call to the
+``trigger_error()`` PHP function). By default, they are silenced and never
+displayed nor logged.
+
+To remove all deprecated feature usages from your templates, write and run a
+script along the lines of the following::
+
+    require_once __DIR__.'/vendor/autoload.php';
+
+    $twig = create_your_twig_env();
+
+    $deprecations = new \Twig\Util\DeprecationCollector($twig);
+
+    print_r($deprecations->collectDir(__DIR__.'/templates'));
+
+The ``collectDir()`` method compiles all templates found in a directory,
+catches deprecation notices, and return them.
+
+.. tip::
+
+    If your templates are not stored on the filesystem, use the ``collect()``
+    method instead. ``collect()`` takes a ``Traversable`` which must return
+    template names as keys and template contents as values (as done by
+    ``\Twig\Util\TemplateDirIterator``).
+
+However, this code won't find all deprecations (like using deprecated some Twig
+classes). To catch all notices, register a custom error handler like the one
+below::
+
+    $deprecations = [];
+    set_error_handler(function ($type, $msg) use (&$deprecations) {
+        if (E_USER_DEPRECATED === $type) {
+            $deprecations[] = $msg;
+        }
+    });
+
+    // run your application
+
+    print_r($deprecations);
+
+Note that most deprecation notices are triggered during **compilation**, so
+they won't be generated when templates are already cached.
+
+.. tip::
+
+    If you want to manage the deprecation notices from your PHPUnit tests, have
+    a look at the `symfony/phpunit-bridge
+    <https://github.com/symfony/phpunit-bridge>`_ package, which eases the
+    process.
+
+Making a Layout conditional
+---------------------------
+
+Working with Ajax means that the same content is sometimes displayed as is,
+and sometimes decorated with a layout. As Twig layout template names can be
+any valid expression, you can pass a variable that evaluates to ``true`` when
+the request is made via Ajax and choose the layout accordingly:
+
+.. code-block:: twig
+
+    {% extends request.ajax ? "base_ajax.html" : "base.html" %}
+
+    {% block content %}
+        This is the content to be displayed.
+    {% endblock %}
+
+Making an Include dynamic
+-------------------------
+
+When including a template, its name does not need to be a string. For
+instance, the name can depend on the value of a variable:
+
+.. code-block:: twig
+
+    {% include var ~ '_foo.html' %}
+
+If ``var`` evaluates to ``index``, the ``index_foo.html`` template will be
+rendered.
+
+As a matter of fact, the template name can be any valid expression, such as
+the following:
+
+.. code-block:: twig
+
+    {% include var|default('index') ~ '_foo.html' %}
+
+Overriding a Template that also extends itself
+----------------------------------------------
+
+A template can be customized in two different ways:
+
+* *Inheritance*: A template *extends* a parent template and overrides some
+  blocks;
+
+* *Replacement*: If you use the filesystem loader, Twig loads the first
+  template it finds in a list of configured directories; a template found in a
+  directory *replaces* another one from a directory further in the list.
+
+But how do you combine both: *replace* a template that also extends itself
+(aka a template in a directory further in the list)?
+
+Let's say that your templates are loaded from both ``.../templates/mysite``
+and ``.../templates/default`` in this order. The ``page.twig`` template,
+stored in ``.../templates/default`` reads as follows:
+
+.. code-block:: twig
+
+    {# page.twig #}
+    {% extends "layout.twig" %}
+
+    {% block content %}
+    {% endblock %}
+
+You can replace this template by putting a file with the same name in
+``.../templates/mysite``. And if you want to extend the original template, you
+might be tempted to write the following:
+
+.. code-block:: twig
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "page.twig" %} {# from .../templates/default #}
+
+However, this will not work as Twig will always load the template from
+``.../templates/mysite``.
+
+It turns out it is possible to get this to work, by adding a directory right
+at the end of your template directories, which is the parent of all of the
+other directories: ``.../templates`` in our case. This has the effect of
+making every template file within our system uniquely addressable. Most of the
+time you will use the "normal" paths, but in the special case of wanting to
+extend a template with an overriding version of itself we can reference its
+parent's full, unambiguous template path in the extends tag:
+
+.. code-block:: twig
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "default/page.twig" %} {# from .../templates #}
+
+.. note::
+
+    This recipe was inspired by the following Django wiki page:
+    https://code.djangoproject.com/wiki/ExtendingTemplates
+
+Customizing the Syntax
+----------------------
+
+Twig allows some syntax customization for the block delimiters. It's **not**
+recommended to use this feature as templates will be tied with your custom
+syntax. But for specific projects, it can make sense to change the defaults.
+
+To change the block delimiters, you need to create your own lexer object::
+
+    $twig = new \Twig\Environment(...);
+
+    $lexer = new \Twig\Lexer($twig, [
+        'tag_comment'   => ['{#', '#}'],
+        'tag_block'     => ['{%', '%}'],
+        'tag_variable'  => ['{{', '}}'],
+        'interpolation' => ['#{', '}'],
+    ]);
+    $twig->setLexer($lexer);
+
+Here are some configuration example that simulates some other template engines
+syntax::
+
+    // Ruby erb syntax
+    $lexer = new \Twig\Lexer($twig, [
+        'tag_comment'  => ['<%#', '%>'],
+        'tag_block'    => ['<%', '%>'],
+        'tag_variable' => ['<%=', '%>'],
+    ]);
+
+    // SGML Comment Syntax
+    $lexer = new \Twig\Lexer($twig, [
+        'tag_comment'  => ['<!--#', '-->'],
+        'tag_block'    => ['<!--', '-->'],
+        'tag_variable' => ['${', '}'],
+    ]);
+
+    // Smarty like
+    $lexer = new \Twig\Lexer($twig, [
+        'tag_comment'  => ['{*', '*}'],
+        'tag_block'    => ['{', '}'],
+        'tag_variable' => ['{$', '}'],
+    ]);
+
+Using dynamic Object Properties
+-------------------------------
+
+When Twig encounters a variable like ``article.title``, it tries to find a
+``title`` public property in the ``article`` object.
+
+It also works if the property does not exist but is rather defined dynamically
+thanks to the magic ``__get()`` method; you need to also implement the
+``__isset()`` magic method like shown in the following snippet of code::
+
+    class Article
+    {
+        public function __get($name)
+        {
+            if ('title' == $name) {
+                return 'The title';
+            }
+
+            // throw some kind of error
+        }
+
+        public function __isset($name)
+        {
+            if ('title' == $name) {
+                return true;
+            }
+
+            return false;
+        }
+    }
+
+Accessing the parent Context in Nested Loops
+--------------------------------------------
+
+Sometimes, when using nested loops, you need to access the parent context. The
+parent context is always accessible via the ``loop.parent`` variable. For
+instance, if you have the following template data::
+
+    $data = [
+        'topics' => [
+            'topic1' => ['Message 1 of topic 1', 'Message 2 of topic 1'],
+            'topic2' => ['Message 1 of topic 2', 'Message 2 of topic 2'],
+        ],
+    ];
+
+And the following template to display all messages in all topics:
+
+.. code-block:: twig
+
+    {% for topic, messages in topics %}
+        * {{ loop.index }}: {{ topic }}
+      {% for message in messages %}
+          - {{ loop.parent.loop.index }}.{{ loop.index }}: {{ message }}
+      {% endfor %}
+    {% endfor %}
+
+The output will be similar to:
+
+.. code-block:: text
+
+    * 1: topic1
+      - 1.1: The message 1 of topic 1
+      - 1.2: The message 2 of topic 1
+    * 2: topic2
+      - 2.1: The message 1 of topic 2
+      - 2.2: The message 2 of topic 2
+
+In the inner loop, the ``loop.parent`` variable is used to access the outer
+context. So, the index of the current ``topic`` defined in the outer for loop
+is accessible via the ``loop.parent.loop.index`` variable.
+
+Defining undefined Functions, Filters, and Tags on the Fly
+----------------------------------------------------------
+
+.. versionadded:: 3.2
+
+    The ``registerUndefinedTokenParserCallback()`` method was added in Twig
+    3.2.
+
+When a function/filter/tag is not defined, Twig defaults to throw a
+``\Twig\Error\SyntaxError`` exception. However, it can also call a `callback`_
+(any valid PHP callable) which should return a function/filter/tag.
+
+For tags, register callbacks with ``registerUndefinedTokenParserCallback()``.
+For filters, register callbacks with ``registerUndefinedFilterCallback()``.
+For functions, use ``registerUndefinedFunctionCallback()``::
+
+    // auto-register all native PHP functions as Twig functions
+    // NEVER do this in a project as it's NOT secure
+    $twig->registerUndefinedFunctionCallback(function ($name) {
+        if (function_exists($name)) {
+            return new \Twig\TwigFunction($name, $name);
+        }
+
+        return false;
+    });
+
+If the callable is not able to return a valid function/filter/tag, it must
+return ``false``.
+
+If you register more than one callback, Twig will call them in turn until one
+does not return ``false``.
+
+.. tip::
+
+    As the resolution of functions/filters/tags is done during compilation,
+    there is no overhead when registering these callbacks.
+
+Validating the Template Syntax
+------------------------------
+
+When template code is provided by a third-party (through a web interface for
+instance), it might be interesting to validate the template syntax before
+saving it. If the template code is stored in a ``$template`` variable, here is
+how you can do it::
+
+    try {
+        $twig->parse($twig->tokenize(new \Twig\Source($template)));
+
+        // the $template is valid
+    } catch (\Twig\Error\SyntaxError $e) {
+        // $template contains one or more syntax errors
+    }
+
+If you iterate over a set of files, you can pass the filename to the
+``tokenize()`` method to get the filename in the exception message::
+
+    foreach ($files as $file) {
+        try {
+            $twig->parse($twig->tokenize(new \Twig\Source($template, $file->getFilename(), $file)));
+
+            // the $template is valid
+        } catch (\Twig\Error\SyntaxError $e) {
+            // $template contains one or more syntax errors
+        }
+    }
+
+.. note::
+
+    This method won't catch any sandbox policy violations because the policy
+    is enforced during template rendering (as Twig needs the context for some
+    checks like allowed methods on objects).
+
+Refreshing modified Templates when OPcache or APC is enabled
+------------------------------------------------------------
+
+When using OPcache with ``opcache.validate_timestamps`` set to ``0`` or APC
+with ``apc.stat`` set to ``0`` and Twig cache enabled, clearing the template
+cache won't update the cache.
+
+To get around this, force Twig to invalidate the bytecode cache::
+
+    $twig = new \Twig\Environment($loader, [
+        'cache' => new \Twig\Cache\FilesystemCache('/some/cache/path', \Twig\Cache\FilesystemCache::FORCE_BYTECODE_INVALIDATION),
+        // ...
+    ]);
+
+Reusing a stateful Node Visitor
+-------------------------------
+
+When attaching a visitor to a ``\Twig\Environment`` instance, Twig uses it to
+visit *all* templates it compiles. If you need to keep some state information
+around, you probably want to reset it when visiting a new template.
+
+This can be achieved with the following code::
+
+    protected $someTemplateState = [];
+
+    public function enterNode(\Twig\Node\Node $node, \Twig\Environment $env)
+    {
+        if ($node instanceof \Twig\Node\ModuleNode) {
+            // reset the state as we are entering a new template
+            $this->someTemplateState = [];
+        }
+
+        // ...
+
+        return $node;
+    }
+
+Using a Database to store Templates
+-----------------------------------
+
+If you are developing a CMS, templates are usually stored in a database. This
+recipe gives you a simple PDO template loader you can use as a starting point
+for your own.
+
+First, let's create a temporary in-memory SQLite3 database to work with::
+
+    $dbh = new PDO('sqlite::memory:');
+    $dbh->exec('CREATE TABLE templates (name STRING, source STRING, last_modified INTEGER)');
+    $base = '{% block content %}{% endblock %}';
+    $index = '
+    {% extends "base.twig" %}
+    {% block content %}Hello {{ name }}{% endblock %}
+    ';
+    $now = time();
+    $dbh->prepare('INSERT INTO templates (name, source, last_modified) VALUES (?, ?, ?)')->execute(['base.twig', $base, $now]);
+    $dbh->prepare('INSERT INTO templates (name, source, last_modified) VALUES (?, ?, ?)')->execute(['index.twig', $index, $now]);
+
+We have created a simple ``templates`` table that hosts two templates:
+``base.twig`` and ``index.twig``.
+
+Now, let's define a loader able to use this database::
+
+    class DatabaseTwigLoader implements \Twig\Loader\LoaderInterface
+    {
+        protected $dbh;
+
+        public function __construct(PDO $dbh)
+        {
+            $this->dbh = $dbh;
+        }
+
+        public function getSourceContext(string $name): Source
+        {
+            if (false === $source = $this->getValue('source', $name)) {
+                throw new \Twig\Error\LoaderError(sprintf('Template "%s" does not exist.', $name));
+            }
+
+            return new \Twig\Source($source, $name);
+        }
+
+        public function exists(string $name)
+        {
+            return $name === $this->getValue('name', $name);
+        }
+
+        public function getCacheKey(string $name): string
+        {
+            return $name;
+        }
+
+        public function isFresh(string $name, int $time): bool
+        {
+            if (false === $lastModified = $this->getValue('last_modified', $name)) {
+                return false;
+            }
+
+            return $lastModified <= $time;
+        }
+
+        protected function getValue($column, $name)
+        {
+            $sth = $this->dbh->prepare('SELECT '.$column.' FROM templates WHERE name = :name');
+            $sth->execute([':name' => (string) $name]);
+
+            return $sth->fetchColumn();
+        }
+    }
+
+Finally, here is an example on how you can use it::
+
+    $loader = new DatabaseTwigLoader($dbh);
+    $twig = new \Twig\Environment($loader);
+
+    echo $twig->render('index.twig', ['name' => 'Fabien']);
+
+Using different Template Sources
+--------------------------------
+
+This recipe is the continuation of the previous one. Even if you store the
+contributed templates in a database, you might want to keep the original/base
+templates on the filesystem. When templates can be loaded from different
+sources, you need to use the ``\Twig\Loader\ChainLoader`` loader.
+
+As you can see in the previous recipe, we reference the template in the exact
+same way as we would have done it with a regular filesystem loader. This is
+the key to be able to mix and match templates coming from the database, the
+filesystem, or any other loader for that matter: the template name should be a
+logical name, and not the path from the filesystem::
+
+    $loader1 = new DatabaseTwigLoader($dbh);
+    $loader2 = new \Twig\Loader\ArrayLoader([
+        'base.twig' => '{% block content %}{% endblock %}',
+    ]);
+    $loader = new \Twig\Loader\ChainLoader([$loader1, $loader2]);
+
+    $twig = new \Twig\Environment($loader);
+
+    echo $twig->render('index.twig', ['name' => 'Fabien']);
+
+Now that the ``base.twig`` templates is defined in an array loader, you can
+remove it from the database, and everything else will still work as before.
+
+Loading a Template from a String
+--------------------------------
+
+From a template, you can load a template stored in a string via the
+``template_from_string`` function (via the
+``\Twig\Extension\StringLoaderExtension`` extension):
+
+.. code-block:: twig
+
+    {{ include(template_from_string("Hello {{ name }}")) }}
+
+From PHP, it's also possible to load a template stored in a string via
+``\Twig\Environment::createTemplate()``::
+
+    $template = $twig->createTemplate('hello {{ name }}');
+    echo $template->render(['name' => 'Fabien']);
+
+Using Twig and AngularJS in the same Templates
+----------------------------------------------
+
+Mixing different template syntaxes in the same file is not a recommended
+practice as both AngularJS and Twig use the same delimiters in their syntax:
+``{{`` and ``}}``.
+
+Still, if you want to use AngularJS and Twig in the same template, there are
+two ways to make it work depending on the amount of AngularJS you need to
+include in your templates:
+
+* Escaping the AngularJS delimiters by wrapping AngularJS sections with the
+  ``{% verbatim %}`` tag or by escaping each delimiter via ``{{ '{{' }}`` and
+  ``{{ '}}' }}``;
+
+* Changing the delimiters of one of the template engines (depending on which
+  engine you introduced last):
+
+  * For AngularJS, change the interpolation tags using the
+    ``interpolateProvider`` service, for instance at the module initialization
+    time:
+
+    ..  code-block:: javascript
+
+        angular.module('myApp', []).config(function($interpolateProvider) {
+            $interpolateProvider.startSymbol('{[').endSymbol(']}');
+        });
+
+  * For Twig, change the delimiters via the ``tag_variable`` Lexer option::
+
+        $env->setLexer(new \Twig\Lexer($env, [
+            'tag_variable' => ['{[', ']}'],
+        ]));
+

+``autoescape``
+==============
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the ``autoescape`` tag:
+
+.. code-block:: twig
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block
+        using the HTML strategy
+    {% endautoescape %}
+
+    {% autoescape 'html' %}
+        Everything will be automatically escaped in this block
+        using the HTML strategy
+    {% endautoescape %}
+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block
+        using the js escaping strategy
+    {% endautoescape %}
+
+    {% autoescape false %}
+        Everything will be outputted as is in this block
+    {% endautoescape %}
+
+When automatic escaping is enabled everything is escaped by default except for
+values explicitly marked as safe. Those can be marked in the template by using
+the :doc:`raw<../filters/raw>` filter:
+
+.. code-block:: twig
+
+    {% autoescape %}
+        {{ safe_value|raw }}
+    {% endautoescape %}
+
+Functions returning template data (like :doc:`macros<macro>` and
+:doc:`parent<../functions/parent>`) always return safe markup.
+
+.. note::
+
+    Twig is smart enough to not escape an already escaped value by the
+    :doc:`escape<../filters/escape>` filter.
+
+.. note::
+
+    Twig does not escape static expressions:
+
+    .. code-block:: html+twig
+
+        {% set hello = "<strong>Hello</strong>" %}
+        {{ hello }}
+        {{ "<strong>world</strong>" }}
+
+    Will be rendered "<strong>Hello</strong> **world**".
+
+.. note::
+
+    The chapter :doc:`Twig for Developers<../api>` gives more information
+    about when and how automatic escaping is applied.

+``cache``
+=========
+
+.. versionadded:: 3.2
+
+    The ``cache`` tag was added in Twig 3.2.
+
+The ``cache`` tag tells Twig to cache a template fragment:
+
+.. code-block:: twig
+
+    {% cache "cache key" %}
+        Cached forever (depending on the cache implementation)
+    {% endcache %}
+
+If you want to expire the cache after a certain amount of time, specify an
+expiration in seconds via the ``ttl()`` modifier:
+
+.. code-block:: twig
+
+    {% cache "cache key" ttl(300) %}
+        Cached for 300 seconds
+    {% endcache %}
+
+The cache key can be any string that does not use the following reserved
+characters ``{}()/\@:``; a good practice is to embed some useful information in
+the key that allows the cache to automatically expire when it must be
+refreshed:
+
+* Give each cache a unique name and namespace it like your templates;
+
+* Embed an integer that you increment whenever the template code changes (to
+  automatically invalidate all current caches);
+
+* Embed a unique key that is updated whenever the variables used in the
+  template code changes.
+
+For instance, I would use ``{% cache "blog_post;v1;" ~ post.id ~ ";" ~
+post.updated_at %}`` to cache a blog content template fragment where
+``blog_post`` describes the template fragment, ``v1`` represents the first
+version of the template code, ``post.id`` represent the id of the blog post,
+and ``post.updated_at`` returns a timestamp that represents the time where the
+blog post was last modified.
+
+Using such a strategy for naming cache keys allows to avoid using a ``ttl``.
+It's like using a "validation" strategy instead of an "expiration" strategy as
+we do for HTTP caches.
+
+If your cache implementation supports tags, you can also tag your cache items:
+
+.. code-block:: twig
+
+    {% cache "cache key" tags('blog') %}
+        Some code
+    {% endcache %}
+
+    {% cache "cache key" tags(['cms', 'blog']) %}
+        Some code
+    {% endcache %}
+
+The ``cache`` tag creates a new "scope" for variables, meaning that the changes
+are local to the template fragment:
+
+.. code-block:: twig
+
+    {% set count = 1 %}
+
+    {% cache "cache key" tags('blog') %}
+        {# Won't affect the value of count outside of the cache tag #}
+        {% set count = 2 %}
+        Some code
+    {% endcache %}
+
+    {# Displays 1 #}
+    {{ count }}
+
+.. note::
+
+    The ``cache`` tag is part of the ``CacheExtension`` which is not installed
+    by default. Install it first:
+
+    .. code-block:: bash
+
+        $ composer require twig/cache-extra
+
+    On Symfony projects, you can automatically enable it by installing the
+    ``twig/extra-bundle``:
+
+    .. code-block:: bash
+
+        $ composer require twig/extra-bundle
+
+    Or add the extension explicitly on the Twig environment::
+
+        use Twig\Extra\Cache\CacheExtension;
+
+        $twig = new \Twig\Environment(...);
+        $twig->addExtension(new CacheExtension());
+
+    If you are not using Symfony, you must also register the extension runtime::
+
+        use Symfony\Component\Cache\Adapter\FilesystemAdapter;
+        use Symfony\Component\Cache\Adapter\TagAwareAdapter;
+        use Twig\Extra\Cache\CacheRuntime;
+        use Twig\RuntimeLoader\RuntimeLoaderInterface;
+
+        $twig->addRuntimeLoader(new class implements RuntimeLoaderInterface {
+            public function load($class) {
+                if (CacheRuntime::class === $class) {
+                    return new CacheRuntime(new TagAwareAdapter(new FilesystemAdapter()));
+                }
+            }
+        });

+``embed``
+=========
+
+The ``embed`` tag combines the behavior of :doc:`include<include>` and
+:doc:`extends<extends>`.
+It allows you to include another template's contents, just like ``include``
+does. But it also allows you to override any block defined inside the
+included template, like when extending a template.
+
+Think of an embedded template as a "micro layout skeleton".
+
+.. code-block:: twig
+
+    {% embed "teasers_skeleton.twig" %}
+        {# These blocks are defined in "teasers_skeleton.twig" #}
+        {# and we override them right here:                    #}
+        {% block left_teaser %}
+            Some content for the left teaser box
+        {% endblock %}
+        {% block right_teaser %}
+            Some content for the right teaser box
+        {% endblock %}
+    {% endembed %}
+
+The ``embed`` tag takes the idea of template inheritance to the level of
+content fragments. While template inheritance allows for "document skeletons",
+which are filled with life by child templates, the ``embed`` tag allows you to
+create "skeletons" for smaller units of content and re-use and fill them
+anywhere you like.
+
+Since the use case may not be obvious, let's look at a simplified example.
+Imagine a base template shared by multiple HTML pages, defining a single block
+named "content":
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │

+    │           │                     │   │

+    │                                     │
+    └─────────────────────────────────────┘
+
+Some pages ("foo" and "bar") share the same content structure -
+two vertically stacked boxes:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │

+    │           │ └─────────────────┘ │   │
+    │           │ ┌─ block "bottom" ┐ │   │

+    │                                     │
+    └─────────────────────────────────────┘
+
+While other pages ("boom" and "baz") share a different content structure -
+two boxes side by side:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │

+
+Without the ``embed`` tag, you have two ways to design your templates:
+
+* Create two "intermediate" base templates that extend the master layout
+  template: one with vertically stacked boxes to be used by the "foo" and
+  "bar" pages and another one with side-by-side boxes for the "boom" and
+  "baz" pages.
+
+* Embed the markup for the top/bottom and left/right boxes into each page
+  template directly.
+
+These two solutions do not scale well because they each have a major drawback:
+
+* The first solution may indeed work for this simplified example. But imagine
+  we add a sidebar, which may again contain different, recurring structures
+  of content. Now we would need to create intermediate base templates for
+  all occurring combinations of content structure and sidebar structure...
+  and so on.
+
+* The second solution involves duplication of common code with all its negative
+  consequences: any change involves finding and editing all affected copies
+  of the structure, correctness has to be verified for each copy, copies may
+  go out of sync by careless modifications etc.
+
+In such a situation, the ``embed`` tag comes in handy. The common layout
+code can live in a single base template, and the two different content structures,
+let's call them "micro layouts" go into separate templates which are embedded
+as necessary:
+
+Page template ``foo.twig``:
+
+.. code-block:: twig
+
+    {% extends "layout_skeleton.twig" %}
+
+    {% block content %}
+        {% embed "vertical_boxes_skeleton.twig" %}
+            {% block top %}
+                Some content for the top box
+            {% endblock %}
+
+            {% block bottom %}
+                Some content for the bottom box
+            {% endblock %}
+        {% endembed %}
+    {% endblock %}
+
+And here is the code for ``vertical_boxes_skeleton.twig``:
+
+.. code-block:: html+twig
+
+    <div class="top_box">
+        {% block top %}
+            Top box default content
+        {% endblock %}
+    </div>
+
+    <div class="bottom_box">
+        {% block bottom %}
+            Bottom box default content
+        {% endblock %}
+    </div>
+
+The goal of the ``vertical_boxes_skeleton.twig`` template being to factor
+out the HTML markup for the boxes.
+
+The ``embed`` tag takes the exact same arguments as the ``include`` tag:
+
+.. code-block:: twig
+
+    {% embed "base" with {'foo': 'bar'} %}
+        ...
+    {% endembed %}
+
+    {% embed "base" with {'foo': 'bar'} only %}
+        ...
+    {% endembed %}
+
+    {% embed "base" ignore missing %}
+        ...
+    {% endembed %}
+
+.. warning::
+
+    As embedded templates do not have "names", auto-escaping strategies based
+    on the template name won't work as expected if you change the context (for
+    instance, if you embed a CSS/JavaScript template into an HTML one). In that
+    case, explicitly set the default auto-escaping strategy with the
+    ``autoescape`` tag.

+``extends``
+===========
+
+The ``extends`` tag can be used to extend a template from another one.
+
+.. note::
+
+    Like PHP, Twig does not support multiple inheritance. So you can only have
+    one extends tag called per rendering. However, Twig supports horizontal
+    :doc:`reuse<use>`.
+
+Let's define a base template, ``base.html``, which defines a simple HTML
+skeleton document:
+
+.. code-block:: html+twig
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css"/>
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<block>` tags define four blocks that child
+templates can fill in.
+
+All the ``block`` tag does is to tell the template engine that a child
+template may override those portions of the template.
+
+Child Template
+--------------
+
+A child template might look like this:
+
+.. code-block:: html+twig
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome on my awesome homepage.
+        </p>
+    {% endblock %}
+
+The ``extends`` tag is the key here. It tells the template engine that this
+template "extends" another template. When the template system evaluates this
+template, first it locates the parent. The extends tag should be the first tag
+in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+You can't define multiple ``block`` tags with the same name in the same
+template. This limitation exists because a block tag works in "both"
+directions. That is, a block tag doesn't just provide a hole to fill - it also
+defines the content that fills the hole in the *parent*. If there were two
+similarly-named ``block`` tags in a template, that template's parent wouldn't
+know which one of the blocks' content to use.
+
+If you want to print a block multiple times you can however use the
+``block`` function:
+
+.. code-block:: html+twig
+
+    <title>{% block title %}{% endblock %}</title>
+    <h1>{{ block('title') }}</h1>
+    {% block body %}{% endblock %}
+
+Parent Blocks
+-------------
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<../functions/parent>` function. This gives back the results of
+the parent block:
+
+.. code-block:: html+twig
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+Named Block End-Tags
+--------------------
+
+Twig allows you to put the name of the block after the end tag for better
+readability (the name after the ``endblock`` word must match the block name):
+
+.. code-block:: twig
+
+    {% block sidebar %}
+        {% block inner_sidebar %}
+            ...
+        {% endblock inner_sidebar %}
+    {% endblock sidebar %}
+
+Block Nesting and Scope
+-----------------------
+
+Blocks can be nested for more complex layouts. Per default, blocks have access
+to variables from outer scopes:
+
+.. code-block:: html+twig
+
+    {% for item in seq %}
+        <li>{% block loop_item %}{{ item }}{% endblock %}</li>
+    {% endfor %}
+
+Block Shortcuts
+---------------
+
+For blocks with little content, it's possible to use a shortcut syntax. The
+following constructs do the same thing:
+
+.. code-block:: twig
+
+    {% block title %}
+        {{ page_title|title }}
+    {% endblock %}
+
+.. code-block:: twig
+
+    {% block title page_title|title %}
+
+Dynamic Inheritance
+-------------------
+
+Twig supports dynamic inheritance by using a variable as the base template:
+
+.. code-block:: twig
+
+    {% extends some_var %}
+
+If the variable evaluates to a ``\Twig\Template`` or a ``\Twig\TemplateWrapper``
+instance, Twig will use it as the parent template::
+
+    // {% extends layout %}
+
+    $layout = $twig->load('some_layout_template.twig');
+
+    $twig->display('template.twig', ['layout' => $layout]);
+
+You can also provide a list of templates that are checked for existence. The
+first template that exists will be used as a parent:
+
+.. code-block:: twig
+
+    {% extends ['layout.html', 'base_layout.html'] %}
+
+Conditional Inheritance
+-----------------------
+
+As the template name for the parent can be any valid Twig expression, it's
+possible to make the inheritance mechanism conditional:
+
+.. code-block:: twig
+
+    {% extends standalone ? "minimum.html" : "base.html" %}
+
+In this example, the template will extend the "minimum.html" layout template
+if the ``standalone`` variable evaluates to ``true``, and "base.html"
+otherwise.
+
+How do blocks work?
+-------------------
+
+A block provides a way to change how a certain part of a template is rendered
+but it does not interfere in any way with the logic around it.
+
+Let's take the following example to illustrate how a block works and more
+importantly, how it does not work:
+
+.. code-block:: html+twig
+
+    {# base.twig #}
+    {% for post in posts %}
+        {% block post %}
+            <h1>{{ post.title }}</h1>
+            <p>{{ post.body }}</p>
+        {% endblock %}
+    {% endfor %}
+
+If you render this template, the result would be exactly the same with or
+without the ``block`` tag. The ``block`` inside the ``for`` loop is just a way
+to make it overridable by a child template:
+
+.. code-block:: html+twig
+
+    {# child.twig #}
+    {% extends "base.twig" %}
+
+    {% block post %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endblock %}
+
+Now, when rendering the child template, the loop is going to use the block
+defined in the child template instead of the one defined in the base one; the
+executed template is then equivalent to the following one:
+
+.. code-block:: html+twig
+
+    {% for post in posts %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endfor %}
+
+Let's take another example: a block included within an ``if`` statement:
+
+.. code-block:: html+twig
+
+    {% if posts is empty %}
+        {% block head %}
+            {{ parent() }}
+
+            <meta name="robots" content="noindex, follow">
+        {% endblock head %}
+    {% endif %}
+
+Contrary to what you might think, this template does not define a block
+conditionally; it just makes overridable by a child template the output of
+what will be rendered when the condition is ``true``.
+
+If you want the output to be displayed conditionally, use the following
+instead:
+
+.. code-block:: html+twig
+
+    {% block head %}
+        {{ parent() }}
+
+        {% if posts is empty %}
+            <meta name="robots" content="noindex, follow">
+        {% endif %}
+    {% endblock head %}
+
+.. seealso::

+Loop over each item in a sequence. For example, to display a list of users

+    <ul>
+        {% for user in users %}

+    </ul>
+
+.. note::
+
+    A sequence can be either an array or an object implementing the
+    ``Traversable`` interface.
+
+If you do need to iterate over a sequence of numbers, you can use the ``..``
+operator:
+
+.. code-block:: twig
+
+    {% for i in 0..10 %}
+        * {{ i }}
+    {% endfor %}

+
+.. code-block:: twig
+
+    {% for letter in 'a'..'z' %}
+        * {{ letter }}
+    {% endfor %}
+
+The ``..`` operator can take any expression at both sides:
+
+.. code-block:: twig
+
+    {% for letter in 'a'|upper..'z'|upper %}
+        * {{ letter }}
+    {% endfor %}
+
+.. tip:
+
+    If you need a step different from 1, you can use the ``range`` function
+    instead.
+
+The `loop` variable
+-------------------
+
+Inside of a ``for`` loop block you can access some special variables:
+
+===================== =============================================================
+Variable              Description
+===================== =============================================================
+``loop.index``        The current iteration of the loop. (1 indexed)
+``loop.index0``       The current iteration of the loop. (0 indexed)
+``loop.revindex``     The number of iterations from the end of the loop (1 indexed)
+``loop.revindex0``    The number of iterations from the end of the loop (0 indexed)
+``loop.first``        True if first iteration
+``loop.last``         True if last iteration
+``loop.length``       The number of items in the sequence
+``loop.parent``       The parent context
+===================== =============================================================
+
+.. code-block:: twig
+
+    {% for user in users %}
+        {{ loop.index }} - {{ user.username }}
+    {% endfor %}
+
+.. note::
+
+    The ``loop.length``, ``loop.revindex``, ``loop.revindex0``, and
+    ``loop.last`` variables are only available for PHP arrays, or objects that
+    implement the ``Countable`` interface.
+
+The `else` Clause
+-----------------
+
+If no iteration took place because the sequence was empty, you can render a
+replacement block by using ``else``:
+
+.. code-block:: html+twig
+
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% else %}
+            <li><em>no user found</em></li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys
+-------------------
+
+By default, a loop iterates over the values of the sequence. You can iterate
+on keys by using the ``keys`` filter:
+
+.. code-block:: html+twig
+
+    <h1>Members</h1>
+    <ul>
+        {% for key in users|keys %}
+            <li>{{ key }}</li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys and Values
+------------------------------
+
+You can also access both keys and values:
+
+.. code-block:: html+twig
+
+    <h1>Members</h1>
+    <ul>
+        {% for key, user in users %}
+            <li>{{ key }}: {{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+Iterating over a Subset
+-----------------------
+
+You might want to iterate over a subset of values. This can be achieved using
+the :doc:`slice <../filters/slice>` filter:
+
+.. code-block:: html+twig
+
+    <h1>Top Ten Members</h1>
+    <ul>
+        {% for user in users|slice(0, 10) %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>

+``if``
+======
+
+The ``if`` statement in Twig is comparable with the if statements of PHP.
+
+In the simplest form you can use it to test if an expression evaluates to
+``true``:
+
+.. code-block:: html+twig
+
+    {% if online == false %}
+        <p>Our website is in maintenance mode. Please, come back later.</p>
+    {% endif %}
+
+You can also test if an array is not empty:
+
+.. code-block:: html+twig
+
+    {% if users %}
+        <ul>
+            {% for user in users %}
+                <li>{{ user.username|e }}</li>
+            {% endfor %}
+        </ul>
+    {% endif %}
+
+.. note::
+
+    If you want to test if the variable is defined, use ``if users is
+    defined`` instead.
+
+You can also use ``not`` to check for values that evaluate to ``false``:
+
+.. code-block:: html+twig
+
+    {% if not user.subscribed %}
+        <p>You are not subscribed to our mailing list.</p>
+    {% endif %}
+
+For multiple conditions, ``and`` and ``or`` can be used:
+
+.. code-block:: html+twig
+
+    {% if temperature > 18 and temperature < 27 %}
+        <p>It's a nice day for a walk in the park.</p>
+    {% endif %}
+
+For multiple branches ``elseif`` and ``else`` can be used like in PHP. You can
+use more complex ``expressions`` there too:
+
+.. code-block:: twig
+
+    {% if product.stock > 10 %}
+       Available
+    {% elseif product.stock > 0 %}
+       Only {{ product.stock }} left!
+    {% else %}
+       Sold-out!
+    {% endif %}
+
+.. note::
+
+    The rules to determine if an expression is ``true`` or ``false`` are the
+    same as in PHP; here are the edge cases rules:
+
+    ====================== ====================
+    Value                  Boolean evaluation
+    ====================== ====================
+    empty string           false

+    NAN (Not A Number)     true

+    whitespace-only string true
+    string "0" or '0'      false
+    empty array            false
+    null                   false

+``include``
+===========
+
+The ``include`` statement includes a template and outputs the rendered content
+of that file:
+
+.. code-block:: twig
+
+    {% include 'header.html' %}
+        Body
+    {% include 'footer.html' %}
+
+.. note::
+
+    It is recommended to use the :doc:`include<../functions/include>` function
+    instead as it provides the same features with a bit more flexibility:
+
+    * The ``include`` function is semantically more "correct" (including a
+      template outputs its rendered contents in the current scope; a tag should
+      not display anything);
+
+    * The ``include`` function is more "composable":
+
+      .. code-block:: twig
+
+          {# Store a rendered template in a variable #}
+          {% set content %}
+              {% include 'template.html' %}
+          {% endset %}
+          {# vs #}
+          {% set content = include('template.html') %}
+
+          {# Apply filter on a rendered template #}
+          {% apply upper %}
+              {% include 'template.html' %}
+          {% endapply %}
+          {# vs #}
+          {{ include('template.html')|upper }}
+
+    * The ``include`` function does not impose any specific order for
+      arguments thanks to :ref:`named arguments <named-arguments>`.
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+You can add additional variables by passing them after the ``with`` keyword:
+
+.. code-block:: twig
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {% include 'template.html' with {'foo': 'bar'} %}
+
+    {% set vars = {'foo': 'bar'} %}
+    {% include 'template.html' with vars %}
+
+You can disable access to the context by appending the ``only`` keyword:
+
+.. code-block:: twig
+
+    {# only the foo variable will be accessible #}
+    {% include 'template.html' with {'foo': 'bar'} only %}
+
+.. code-block:: twig
+
+    {# no variables will be accessible #}
+    {% include 'template.html' only %}
+
+.. tip::
+
+    When including a template created by an end user, you should consider
+    sandboxing it. More information in the :doc:`Twig for Developers<../api>`
+    chapter and in the :doc:`sandbox<../tags/sandbox>` tag documentation.
+
+The template name can be any valid Twig expression:
+
+.. code-block:: twig
+
+    {% include some_var %}
+    {% include ajax ? 'ajax.html' : 'not_ajax.html' %}
+
+And if the expression evaluates to a ``\Twig\Template`` or a
+``\Twig\TemplateWrapper`` instance, Twig will use it directly::
+
+    // {% include template %}
+
+    $template = $twig->load('some_template.twig');
+
+    $twig->display('template.twig', ['template' => $template]);
+
+You can mark an include with ``ignore missing`` in which case Twig will ignore
+the statement if the template to be included does not exist. It has to be
+placed just after the template name. Here some valid examples:
+
+.. code-block:: twig
+
+    {% include 'sidebar.html' ignore missing %}
+    {% include 'sidebar.html' ignore missing with {'foo': 'bar'} %}
+    {% include 'sidebar.html' ignore missing only %}
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be included:
+
+.. code-block:: twig
+
+    {% include ['page_detailed.html', 'page.html'] %}
+
+If ``ignore missing`` is given, it will fall back to rendering nothing if none
+of the templates exist, otherwise it will throw an exception.

+``macro``
+=========
+
+Macros are comparable with functions in regular programming languages. They
+are useful to reuse template fragments to not repeat yourself.
+
+Macros are defined in regular templates.
+
+Imagine having a generic helper template that define how to render HTML forms
+via macros (called ``forms.html``):
+
+.. code-block:: html+twig
+
+    {% macro input(name, value, type = "text", size = 20) %}
+        <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}"/>
+    {% endmacro %}
+
+    {% macro textarea(name, value, rows = 10, cols = 40) %}
+        <textarea name="{{ name }}" rows="{{ rows }}" cols="{{ cols }}">{{ value|e }}</textarea>
+    {% endmacro %}
+
+Each macro argument can have a default value (here ``text`` is the default value
+for ``type`` if not provided in the call).
+
+Macros differ from native PHP functions in a few ways:
+
+* Arguments of a macro are always optional.
+
+* If extra positional arguments are passed to a macro, they end up in the
+  special ``varargs`` variable as a list of values.
+
+But as with PHP functions, macros don't have access to the current template
+variables.
+
+.. tip::
+
+    You can pass the whole context as an argument by using the special
+    ``_context`` variable.
+
+Importing Macros
+----------------
+
+There are two ways to import macros. You can import the complete template
+containing the macros into a local variable (via the ``import`` tag) or only
+import specific macros from the template (via the ``from`` tag).
+
+To import all macros from a template into a local variable, use the ``import``
+tag:
+
+.. code-block:: twig
+
+    {% import "forms.html" as forms %}
+
+The above ``import`` call imports the ``forms.html`` file (which can contain
+only macros, or a template and some macros), and import the macros as items of
+the ``forms`` local variable.
+
+The macros can then be called at will in the *current* template:
+
+.. code-block:: html+twig
+
+    <p>{{ forms.input('username') }}</p>
+    <p>{{ forms.input('password', null, 'password') }}</p>
+
+Alternatively you can import names from the template into the current namespace
+via the ``from`` tag:
+
+.. code-block:: html+twig
+
+    {% from 'forms.html' import input as input_field, textarea %}
+
+    <p>{{ input_field('password', '', 'password') }}</p>
+    <p>{{ textarea('comment') }}</p>
+
+.. tip::
+
+    When macro usages and definitions are in the same template, you don't need to
+    import the macros as they are automatically available under the special
+    ``_self`` variable:
+
+    .. code-block:: html+twig
+
+        <p>{{ _self.input('password', '', 'password') }}</p>
+
+        {% macro input(name, value, type = "text", size = 20) %}
+            <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}"/>
+        {% endmacro %}
+
+Macros Scoping
+--------------
+
+The scoping rules are the same whether you imported macros via ``import`` or
+``from``.
+
+Imported macros are always **local** to the current template. It means that
+macros are available in all blocks and other macros defined in the current
+template, but they are not available in included templates or child templates;
+you need to explicitly re-import macros in each template.
+
+Imported macros are not available in the body of ``embed`` tags, you need
+to explicitly re-import macros inside the tag.
+
+When calling ``import`` or ``from`` from a ``block`` tag, the imported macros
+are only defined in the current block and they override macros defined at the
+template level with the same names.
+
+When calling ``import`` or ``from`` from a ``macro`` tag, the imported macros
+are only defined in the current macro and they override macros defined at the
+template level with the same names.
+
+Checking if a Macro is defined
+------------------------------
+
+You can check if a macro is defined via the ``defined`` test:
+
+.. code-block:: twig
+
+    {% import "macros.twig" as macros %}
+
+    {% from "macros.twig" import hello %}
+
+    {% if macros.hello is defined -%}
+        OK
+    {% endif %}
+
+    {% if hello is defined -%}
+        OK
+    {% endif %}
+
+Named Macro End-Tags
+--------------------
+
+Twig allows you to put the name of the macro after the end tag for better
+readability (the name after the ``endmacro`` word must match the macro name):
+
+.. code-block:: twig
+
+    {% macro input() %}
+        ...
+    {% endmacro input %}

+``set``
+=======
+
+Inside code blocks you can also assign values to variables. Assignments use
+the ``set`` tag and can have multiple targets.
+
+Here is how you can assign the ``bar`` value to the ``foo`` variable:
+
+.. code-block:: twig
+
+    {% set foo = 'bar' %}
+
+After the ``set`` call, the ``foo`` variable is available in the template like
+any other ones:
+
+.. code-block:: twig
+
+    {# displays bar #}
+    {{ foo }}
+
+The assigned value can be any valid :ref:`Twig expression
+<twig-expressions>`:
+
+.. code-block:: twig
+
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+    {% set foo = 'foo' ~ 'bar' %}
+
+Several variables can be assigned in one block:
+
+.. code-block:: twig
+
+    {% set foo, bar = 'foo', 'bar' %}
+
+    {# is equivalent to #}
+
+    {% set foo = 'foo' %}
+    {% set bar = 'bar' %}
+
+The ``set`` tag can also be used to 'capture' chunks of text:
+
+.. code-block:: html+twig
+
+    {% set foo %}
+        <div id="pagination">
+            ...
+        </div>
+    {% endset %}
+
+.. caution::
+
+    If you enable automatic output escaping, Twig will only consider the
+    content to be safe when capturing chunks of text.
+
+.. note::
+
+    Note that loops are scoped in Twig; therefore a variable declared inside a
+    ``for`` loop is not accessible outside the loop itself:
+
+    .. code-block:: twig
+
+        {% for item in list %}
+            {% set foo = item %}
+        {% endfor %}

+        {# foo is NOT available #}
+
+    If you want to access the variable, just declare it before the loop:

+        {% set foo = "" %}
+        {% for item in list %}

+``use``
+=======
+
+.. note::
+
+    Horizontal reuse is an advanced Twig feature that is hardly ever needed in
+    regular templates. It is mainly used by projects that need to make
+    template blocks reusable without using inheritance.
+
+Template inheritance is one of the most powerful features of Twig but it is
+limited to single inheritance; a template can only extend one other template.
+This limitation makes template inheritance simple to understand and easy to
+debug:
+
+.. code-block:: twig
+
+    {% extends "base.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+Horizontal reuse is a way to achieve the same goal as multiple inheritance,
+but without the associated complexity:
+
+.. code-block:: twig
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+The ``use`` statement tells Twig to import the blocks defined in
+``blocks.html`` into the current template (it's like macros, but for blocks):
+
+.. code-block:: twig
+
+    {# blocks.html #}
+    
+    {% block sidebar %}{% endblock %}
+
+In this example, the ``use`` statement imports the ``sidebar`` block into the
+main template. The code is mostly equivalent to the following one (the
+imported blocks are not outputted automatically):
+
+.. code-block:: twig
+
+    {% extends "base.html" %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+.. note::
+
+    The ``use`` tag only imports a template if it does not extend another
+    template, if it does not define macros, and if the body is empty. But it
+    can *use* other templates.
+
+.. note::
+
+    Because ``use`` statements are resolved independently of the context
+    passed to the template, the template reference cannot be an expression.
+
+The main template can also override any imported block. If the template
+already defines the ``sidebar`` block, then the one defined in ``blocks.html``
+is ignored. To avoid name conflicts, you can rename imported blocks:
+
+.. code-block:: twig
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" with sidebar as base_sidebar, title as base_title %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+The ``parent()`` function automatically determines the correct inheritance
+tree, so it can be used when overriding a block defined in an imported
+template:
+
+.. code-block:: twig
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block sidebar %}
+        {{ parent() }}
+    {% endblock %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+In this example, ``parent()`` will correctly call the ``sidebar`` block from
+the ``blocks.html`` template.
+
+.. tip::
+
+    Renaming allows you to simulate inheritance by calling the "parent" block:
+
+    .. code-block:: twig
+
+        {% extends "base.html" %}
+
+        {% use "blocks.html" with sidebar as parent_sidebar %}
+
+        {% block sidebar %}
+            {{ block('parent_sidebar') }}
+        {% endblock %}
+
+.. note::
+
+    You can use as many ``use`` statements as you want in any given template.
+    If two imported templates define the same block, the latest one wins.

+``with``
+========

+        {% set foo = 42 %}

+Twig for Template Designers
+===========================
+
+This document describes the syntax and semantics of the template engine and
+will be most useful as reference to those creating Twig templates.
+
+Synopsis
+--------
+
+A template is a regular text file. It can generate any text-based format (HTML,
+XML, CSV, LaTeX, etc.). It doesn't have a specific extension, ``.html`` or
+``.xml`` are just fine.
+
+A template contains **variables** or **expressions**, which get replaced with
+values when the template is evaluated, and **tags**, which control the
+template's logic.
+
+Below is a minimal template that illustrates a few basics. We will cover further
+details later on:
+
+.. code-block:: html+twig
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            <title>My Webpage</title>
+        </head>
+        <body>
+            <ul id="navigation">
+            {% for item in navigation %}
+                <li><a href="{{ item.href }}">{{ item.caption }}</a></li>
+            {% endfor %}
+            </ul>
+
+            <h1>My Webpage</h1>
+            {{ a_variable }}
+        </body>
+    </html>
+
+There are two kinds of delimiters: ``{% ... %}`` and ``{{ ... }}``. The first
+one is used to execute statements such as for-loops, the latter outputs the
+result of an expression.
+
+IDEs Integration
+----------------
+
+Many IDEs support syntax highlighting and auto-completion for Twig:
+
+* *Textmate* via the `Twig bundle`_
+* *Vim* via the `Jinja syntax plugin`_ or the `vim-twig plugin`_
+* *Netbeans* via the `Twig syntax plugin`_ (until 7.1, native as of 7.2)
+* *PhpStorm* (native as of 2.1)
+* *Eclipse* via the `Twig plugin`_
+* *Sublime Text* via the `Twig bundle`_
+* *GtkSourceView* via the `Twig language definition`_ (used by gedit and other projects)
+* *Coda* and *SubEthaEdit* via the `Twig syntax mode`_
+* *Coda 2* via the `other Twig syntax mode`_
+* *Komodo* and *Komodo Edit* via the Twig highlight/syntax check mode
+* *Notepad++* via the `Notepad++ Twig Highlighter`_
+* *Emacs* via `web-mode.el`_
+* *Atom* via the `PHP-twig for atom`_
+* *Visual Studio Code* via the `Twig pack`_
+
+Also, `TwigFiddle`_ is an online service that allows you to execute Twig templates
+from a browser; it supports all versions of Twig.
+
+Variables
+---------
+
+The application passes variables to the templates for manipulation in the
+template. Variables may have attributes or elements you can access, too. The
+visual representation of a variable depends heavily on the application providing
+it.
+
+Use a dot (``.``) to access attributes of a variable (methods or properties of a
+PHP object, or items of a PHP array):
+
+.. code-block:: twig
+
+    {{ foo.bar }}
+
+.. note::
+
+    It's important to know that the curly braces are *not* part of the
+    variable but the print statement. When accessing variables inside tags,
+    don't put the braces around them.
+
+.. sidebar:: Implementation
+
+    For convenience's sake ``foo.bar`` does the following things on the PHP
+    layer:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid property;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid method
+      (even if ``bar`` is the constructor - use ``__construct()`` instead);
+    * if not, and if ``foo`` is an object, check that ``getBar`` is a valid method;
+    * if not, and if ``foo`` is an object, check that ``isBar`` is a valid method;
+    * if not, and if ``foo`` is an object, check that ``hasBar`` is a valid method;
+    * if not, return a ``null`` value.
+
+    Twig also supports a specific syntax for accessing items on PHP arrays,
+    ``foo['bar']``:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, return a ``null`` value.
+
+If a variable or attribute does not exist, you will receive a ``null`` value
+when the ``strict_variables`` option is set to ``false``; alternatively, if ``strict_variables``
+is set, Twig will throw an error (see :ref:`environment options<environment_options>`).
+
+.. note::
+
+    If you want to access a dynamic attribute of a variable, use the
+    :doc:`attribute<functions/attribute>` function instead.
+
+    The ``attribute`` function is also useful when the attribute contains
+    special characters (like ``-`` that would be interpreted as the minus
+    operator):
+
+    .. code-block:: twig
+
+        {# equivalent to the non-working foo.data-foo #}
+        {{ attribute(foo, 'data-foo') }}
+
+Global Variables
+~~~~~~~~~~~~~~~~
+
+The following variables are always available in templates:
+
+* ``_self``: references the current template name;
+* ``_context``: references the current context;
+* ``_charset``: references the current charset.
+
+Setting Variables
+~~~~~~~~~~~~~~~~~
+
+You can assign values to variables inside code blocks. Assignments use the
+:doc:`set<tags/set>` tag:
+
+.. code-block:: twig
+
+    {% set foo = 'foo' %}
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+
+Filters
+-------
+
+Variables can be modified by **filters**. Filters are separated from the
+variable by a pipe symbol (``|``). Multiple filters can be chained. The output
+of one filter is applied to the next.
+
+The following example removes all HTML tags from the ``name`` and title-cases
+it:
+
+.. code-block:: twig
+
+    {{ name|striptags|title }}
+
+Filters that accept arguments have parentheses around the arguments. This
+example joins the elements of a list by commas:
+
+.. code-block:: twig
+
+    {{ list|join(', ') }}
+
+To apply a filter on a section of code, wrap it with the
+:doc:`apply<tags/apply>` tag:
+
+.. code-block:: twig
+
+    {% apply upper %}
+        This text becomes uppercase
+    {% endapply %}
+
+Go to the :doc:`filters<filters/index>` page to learn more about built-in
+filters.
+
+Functions
+---------
+
+Functions can be called to generate content. Functions are called by their
+name followed by parentheses (``()``) and may have arguments.
+
+For instance, the ``range`` function returns a list containing an arithmetic
+progression of integers:
+
+.. code-block:: twig
+
+    {% for i in range(0, 3) %}
+        {{ i }},
+    {% endfor %}
+
+Go to the :doc:`functions<functions/index>` page to learn more about the
+built-in functions.
+
+.. _named-arguments:
+
+Named Arguments
+---------------
+
+.. code-block:: twig
+
+    {% for i in range(low=1, high=10, step=2) %}
+        {{ i }},
+    {% endfor %}
+
+Using named arguments makes your templates more explicit about the meaning of
+the values you pass as arguments:
+
+.. code-block:: twig
+
+    {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
+
+    {# versus #}
+
+    {{ data|convert_encoding(from='iso-2022-jp', to='UTF-8') }}
+
+Named arguments also allow you to skip some arguments for which you don't want
+to change the default value:
+
+.. code-block:: twig
+
+    {# the first argument is the date format, which defaults to the global date format if null is passed #}
+    {{ "now"|date(null, "Europe/Paris") }}
+
+    {# or skip the format value by using a named argument for the time zone #}
+    {{ "now"|date(timezone="Europe/Paris") }}
+
+You can also use both positional and named arguments in one call, in which
+case positional arguments must always come before named arguments:
+
+.. code-block:: twig
+
+    {{ "now"|date('d/m/Y H:i', timezone="Europe/Paris") }}
+
+.. tip::
+
+    Each function and filter documentation page has a section where the names
+    of all arguments are listed when supported.
+
+Control Structure
+-----------------
+
+A control structure refers to all those things that control the flow of a
+program - conditionals (i.e. ``if``/``elseif``/``else``), ``for``-loops, as
+well as things like blocks. Control structures appear inside ``{% ... %}``
+blocks.
+
+For example, to display a list of users provided in a variable called
+``users``, use the :doc:`for<tags/for>` tag:
+
+.. code-block:: html+twig
+
+    <h1>Members</h1>
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+The :doc:`if<tags/if>` tag can be used to test an expression:
+
+.. code-block:: html+twig
+
+    {% if users|length > 0 %}
+        <ul>
+            {% for user in users %}
+                <li>{{ user.username|e }}</li>
+            {% endfor %}
+        </ul>
+    {% endif %}
+
+Go to the :doc:`tags<tags/index>` page to learn more about the built-in tags.
+
+Comments
+--------
+
+To comment-out part of a line in a template, use the comment syntax ``{# ...
+#}``. This is useful for debugging or to add information for other template
+designers or yourself:
+
+.. code-block:: twig
+
+    {# note: disabled template because we no longer use this
+        {% for user in users %}
+            ...
+        {% endfor %}
+    #}
+
+Including other Templates
+-------------------------
+
+The :doc:`include<functions/include>` function is useful to include a template
+and return the rendered content of that template into the current one:
+
+.. code-block:: twig
+
+    {{ include('sidebar.html') }}
+
+By default, included templates have access to the same context as the template
+which includes them. This means that any variable defined in the main template
+will be available in the included template too:
+
+.. code-block:: twig
+
+    {% for box in boxes %}
+        {{ include('render_box.html') }}
+    {% endfor %}
+
+The included template ``render_box.html`` is able to access the ``box`` variable.
+
+The name of the template depends on the template loader. For instance, the
+``\Twig\Loader\FilesystemLoader`` allows you to access other templates by giving the
+filename. You can access templates in subdirectories with a slash:
+
+.. code-block:: twig
+
+    {{ include('sections/articles/sidebar.html') }}
+
+This behavior depends on the application embedding Twig.
+
+Template Inheritance
+--------------------
+
+The most powerful part of Twig is template inheritance. Template inheritance
+allows you to build a base "skeleton" template that contains all the common
+elements of your site and defines **blocks** that child templates can
+override.
+
+It's easier to understand the concept by starting with an example.
+
+Let's define a base template, ``base.html``, which defines an HTML skeleton
+document that might be used for a two-column page:
+
+.. code-block:: html+twig
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css"/>
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<tags/block>` tags define four blocks that
+child templates can fill in. All the ``block`` tag does is to tell the
+template engine that a child template may override those portions of the
+template.
+
+A child template might look like this:
+
+.. code-block:: html+twig
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome to my awesome homepage.
+        </p>
+    {% endblock %}
+
+The :doc:`extends<tags/extends>` tag is the key here. It tells the template
+engine that this template "extends" another template. When the template system
+evaluates this template, first it locates the parent. The extends tag should
+be the first tag in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<functions/parent>` function. This gives back the results of the
+parent block:
+
+.. code-block:: html+twig
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+.. tip::
+
+    The documentation page for the :doc:`extends<tags/extends>` tag describes
+    more advanced features like block nesting, scope, dynamic inheritance, and
+    conditional inheritance.
+
+.. note::
+
+    Twig also supports multiple inheritance via "horizontal reuse" with the help
+    of the :doc:`use<tags/use>` tag.
+
+HTML Escaping
+-------------
+
+When generating HTML from templates, there's always a risk that a variable
+will include characters that affect the resulting HTML. There are two
+approaches: manually escaping each variable or automatically escaping
+everything by default.
+
+Twig supports both, automatic escaping is enabled by default.
+
+The automatic escaping strategy can be configured via the
+:ref:`autoescape<environment_options>` option and defaults to ``html``.
+
+Working with Manual Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If manual escaping is enabled, it is **your** responsibility to escape variables
+if needed. What to escape? Any variable that comes from an untrusted source.
+
+Escaping works by using the :doc:`escape<filters/escape>` or ``e`` filter:
+
+.. code-block:: twig
+
+    {{ user.username|e }}
+
+By default, the ``escape`` filter uses the ``html`` strategy, but depending on
+the escaping context, you might want to explicitly use an other strategy:
+
+.. code-block:: twig
+
+    {{ user.username|e('js') }}
+    {{ user.username|e('css') }}
+    {{ user.username|e('url') }}
+    {{ user.username|e('html_attr') }}
+
+Working with Automatic Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the :doc:`autoescape<tags/autoescape>`
+tag:
+
+.. code-block:: twig
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block (using the HTML strategy)
+    {% endautoescape %}
+
+By default, auto-escaping uses the ``html`` escaping strategy. If you output
+variables in other contexts, you need to explicitly escape them with the
+appropriate escaping strategy:
+
+.. code-block:: twig
+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block (using the JS strategy)
+    {% endautoescape %}
+
+Escaping
+--------
+
+It is sometimes desirable or even necessary to have Twig ignore parts it would
+otherwise handle as variables or blocks. For example if the default syntax is
+used and you want to use ``{{`` as raw string in the template and not start a
+variable you have to use a trick.
+
+The easiest way is to output the variable delimiter (``{{``) by using a variable
+expression:
+
+.. code-block:: twig
+
+    {{ '{{' }}
+
+For bigger sections it makes sense to mark a block
+:doc:`verbatim<tags/verbatim>`.
+
+Macros
+------
+
+Macros are comparable with functions in regular programming languages. They are
+useful to reuse HTML fragments to not repeat yourself. They are described in the
+:doc:`macro<tags/macro>` tag documentation.
+
+.. _twig-expressions:
+
+Expressions
+-----------
+
+Twig allows expressions everywhere.
+
+.. note::
+
+    The operator precedence is as follows, with the lowest-precedence operators
+    listed first: ``?:`` (ternary operator), ``b-and``, ``b-xor``, ``b-or``,
+    ``or``, ``and``, ``==``, ``!=``, ``<=>``, ``<``, ``>``, ``>=``, ``<=``,
+    ``in``, ``matches``, ``starts with``, ``ends with``, ``..``, ``+``, ``-``,
+    ``~``, ``*``, ``/``, ``//``, ``%``, ``is`` (tests), ``**``, ``??``, ``|``
+    (filters), ``[]``, and ``.``:
+
+    .. code-block:: twig
+
+        {% set greeting = 'Hello ' %}
+        {% set name = 'Fabien' %}
+
+        {{ greeting ~ name|lower }}   {# Hello fabien #}
+
+        {# use parenthesis to change precedence #}
+        {{ (greeting ~ name)|lower }} {# hello fabien #}
+
+Literals
+~~~~~~~~
+
+The simplest form of expressions are literals. Literals are representations
+for PHP types such as strings, numbers, and arrays. The following literals
+exist:
+
+* ``"Hello World"``: Everything between two double or single quotes is a
+  string. They are useful whenever you need a string in the template (for
+  example as arguments to function calls, filters or just to extend or include
+  a template). A string can contain a delimiter if it is preceded by a
+  backslash (``\``) -- like in ``'It\'s good'``. If the string contains a
+  backslash (e.g. ``'c:\Program Files'``) escape it by doubling it
+  (e.g. ``'c:\\Program Files'``).
+
+* ``42`` / ``42.23``: Integers and floating point numbers are created by
+  writing the number down. If a dot is present the number is a float,
+  otherwise an integer.
+
+* ``["foo", "bar"]``: Arrays are defined by a sequence of expressions
+  separated by a comma (``,``) and wrapped with squared brackets (``[]``).
+
+* ``{"foo": "bar"}``: Hashes are defined by a list of keys and values
+  separated by a comma (``,``) and wrapped with curly braces (``{}``):
+
+  .. code-block:: twig
+
+    {# keys as string #}
+    { 'foo': 'foo', 'bar': 'bar' }
+
+    {# keys as names (equivalent to the previous hash) #}
+    { foo: 'foo', bar: 'bar' }
+
+    {# keys as integer #}
+    { 2: 'foo', 4: 'bar' }
+
+    {# keys can be omitted if it is the same as the variable name #}
+    { foo }
+    {# is equivalent to the following #}
+    { 'foo': foo }
+
+    {# keys as expressions (the expression must be enclosed into parentheses) #}
+    {% set foo = 'foo' %}
+    { (foo): 'foo', (1 + 1): 'bar', (foo ~ 'b'): 'baz' }
+
+* ``true`` / ``false``: ``true`` represents the true value, ``false``
+  represents the false value.
+
+* ``null``: ``null`` represents no specific value. This is the value returned
+  when a variable does not exist. ``none`` is an alias for ``null``.
+
+Arrays and hashes can be nested:
+
+.. code-block:: twig
+
+    {% set foo = [1, {"foo": "bar"}] %}
+
+.. tip::
+
+    Using double-quoted or single-quoted strings has no impact on performance
+    but :ref:`string interpolation <templates-string-interpolation>` is only
+    supported in double-quoted strings.
+
+Math
+~~~~
+
+Twig allows you to do math in templates; the following operators are supported:
+
+* ``+``: Adds two numbers together (the operands are casted to numbers). ``{{
+  1 + 1 }}`` is ``2``.
+
+* ``-``: Subtracts the second number from the first one. ``{{ 3 - 2 }}`` is
+  ``1``.
+
+* ``/``: Divides two numbers. The returned value will be a floating point
+  number. ``{{ 1 / 2 }}`` is ``{{ 0.5 }}``.
+
+* ``%``: Calculates the remainder of an integer division. ``{{ 11 % 7 }}`` is
+  ``4``.
+
+* ``//``: Divides two numbers and returns the floored integer result. ``{{ 20
+  // 7 }}`` is ``2``, ``{{ -20  // 7 }}`` is ``-3`` (this is just syntactic
+  sugar for the :doc:`round<filters/round>` filter).
+
+* ``*``: Multiplies the left operand with the right one. ``{{ 2 * 2 }}`` would
+  return ``4``.
+
+* ``**``: Raises the left operand to the power of the right operand. ``{{ 2 **
+  3 }}`` would return ``8``.
+
+.. _template_logic:
+
+Logic
+~~~~~
+
+You can combine multiple expressions with the following operators:
+
+* ``and``: Returns true if the left and the right operands are both true.
+
+* ``or``: Returns true if the left or the right operand is true.
+
+* ``not``: Negates a statement.
+
+* ``(expr)``: Groups an expression.
+
+.. note::
+
+    Twig also supports bitwise operators (``b-and``, ``b-xor``, and ``b-or``).
+
+.. note::
+
+    Operators are case sensitive.
+
+Comparisons
+~~~~~~~~~~~
+
+The following comparison operators are supported in any expression: ``==``,
+``!=``, ``<``, ``>``, ``>=``, and ``<=``.
+
+You can also check if a string ``starts with`` or ``ends with`` another
+string:
+
+.. code-block:: twig
+
+    {% if 'Fabien' starts with 'F' %}
+    {% endif %}
+
+    {% if 'Fabien' ends with 'n' %}
+    {% endif %}
+
+.. note::
+
+    For complex string comparisons, the ``matches`` operator allows you to use
+    `regular expressions`_:
+
+    .. code-block:: twig
+
+        {% if phone matches '/^[\\d\\.]+$/' %}
+        {% endif %}
+
+Containment Operator
+~~~~~~~~~~~~~~~~~~~~
+
+The ``in`` operator performs containment test. It returns ``true`` if the left
+operand is contained in the right:
+
+.. code-block:: twig
+
+    {# returns true #}
+
+    {{ 1 in [1, 2, 3] }}
+
+    {{ 'cd' in 'abcde' }}
+
+.. tip::
+
+    You can use this filter to perform a containment test on strings, arrays,
+    or objects implementing the ``Traversable`` interface.
+
+To perform a negative test, use the ``not in`` operator:
+
+.. code-block:: twig
+
+    {% if 1 not in [1, 2, 3] %}
+
+    {# is equivalent to #}
+    {% if not (1 in [1, 2, 3]) %}
+
+Test Operator
+~~~~~~~~~~~~~
+
+The ``is`` operator performs tests. Tests can be used to test a variable against
+a common expression. The right operand is name of the test:
+
+.. code-block:: twig
+
+    {# find out if a variable is odd #}
+
+    {{ name is odd }}
+
+Tests can accept arguments too:
+
+.. code-block:: twig
+
+    {% if post.status is constant('Post::PUBLISHED') %}
+
+Tests can be negated by using the ``is not`` operator:
+
+.. code-block:: twig
+
+    {% if post.status is not constant('Post::PUBLISHED') %}
+
+    {# is equivalent to #}
+    {% if not (post.status is constant('Post::PUBLISHED')) %}
+
+Go to the :doc:`tests<tests/index>` page to learn more about the built-in
+tests.
+
+Other Operators
+~~~~~~~~~~~~~~~
+
+The following operators don't fit into any of the other categories:
+
+* ``|``: Applies a filter.
+
+* ``..``: Creates a sequence based on the operand before and after the operator
+  (this is syntactic sugar for the :doc:`range<functions/range>` function):
+
+  .. code-block:: twig
+
+      {{ 1..5 }}
+
+      {# equivalent to #}
+      {{ range(1, 5) }}
+
+  Note that you must use parentheses when combining it with the filter operator
+  due to the :ref:`operator precedence rules <twig-expressions>`:
+
+  .. code-block:: twig
+
+      (1..5)|join(', ')
+
+* ``~``: Converts all operands into strings and concatenates them. ``{{ "Hello
+  " ~ name ~ "!" }}`` would return (assuming ``name`` is ``'John'``) ``Hello
+  John!``.
+
+* ``.``, ``[]``: Gets an attribute of a variable.
+
+* ``?:``: The ternary operator:
+
+  .. code-block:: twig
+
+      {{ foo ? 'yes' : 'no' }}
+      {{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
+      {{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}
+
+* ``??``: The null-coalescing operator:
+
+  .. code-block:: twig
+
+      {# returns the value of foo if it is defined and not null, 'no' otherwise #}
+      {{ foo ?? 'no' }}
+
+.. _templates-string-interpolation:
+
+String Interpolation
+~~~~~~~~~~~~~~~~~~~~
+
+String interpolation (``#{expression}``) allows any valid expression to appear
+within a *double-quoted string*. The result of evaluating that expression is
+inserted into the string:
+
+.. code-block:: twig
+
+    {{ "foo #{bar} baz" }}
+    {{ "foo #{1 + 2} baz" }}
+
+.. _templates-whitespace-control:
+
+Whitespace Control
+------------------
+
+The first newline after a template tag is removed automatically (like in PHP).
+Whitespace is not further modified by the template engine, so each whitespace
+(spaces, tabs, newlines etc.) is returned unchanged.
+
+You can also control whitespace on a per tag level. By using the whitespace
+control modifiers on your tags, you can trim leading and or trailing whitespace.
+
+Twig supports two modifiers:
+
+* *Whitespace trimming* via the ``-`` modifier: Removes all whitespace
+  (including newlines);
+
+* *Line whitespace trimming* via the ``~`` modifier: Removes all whitespace
+  (excluding newlines). Using this modifier on the right disables the default
+  removal of the first newline inherited from PHP.
+
+The modifiers can be used on either side of the tags like in ``{%-`` or ``-%}``
+and they consume all whitespace for that side of the tag. It is possible to use
+the modifiers on one side of a tag or on both sides:
+
+.. code-block:: html+twig
+
+    {% set value = 'no spaces' %}
+    {#- No leading/trailing whitespace -#}
+    {%- if true -%}
+        {{- value -}}
+    {%- endif -%}
+    {# output 'no spaces' #}
+
+    <li>
+        {{ value }}    </li>
+    {# outputs '<li>\n    no spaces    </li>' #}
+
+    <li>
+        {{- value }}    </li>
+    {# outputs '<li>no spaces    </li>' #}
+
+    <li>
+        {{~ value }}    </li>
+    {# outputs '<li>\nno spaces    </li>' #}
+
+.. tip::
+
+    In addition to the whitespace modifiers, Twig also has a ``spaceless`` filter
+    that removes whitespace **between HTML tags**:
+
+    .. code-block:: html+twig
+
+        {% apply spaceless %}
+            <div>
+                <strong>foo bar</strong>
+            </div>
+        {% endapply %}
+
+        {# output will be <div><strong>foo bar</strong></div> #}
